Complete Underfloor Heating Kit
It is possible to include a complete Underfloor Heating Kit to your order. All you need to do is to choose the required size. Additional package, with heating mat, appropriate thermostat, sensor and instructions will be dispatched together with the other goods.

To calculate required mat size you need to get square coverage of the floor and exclude any permanent / fixed fixtures from them. It is also recommended to buy slightly smaller mat than calculated size - you can shape it but cannot cut the cables, therefore too large mat could not be installed.

SUNFLOOR Underfloor Heating
The SUNFLOOR Electric Heating Mat is a unique type of floor heating mat. The system has been designed to be used on an existing tiled floor or an existing finished floor, so that floor heating can still be installed there. The mat is approximately 4 mm thick and can be included in a layer of adhesive without any demolishing or grinding. The mat fits virtually underneath the surface. This decreases the heating time of the floor, that also makes this system suitable for rooms that are not permanently occupied including bathrooms, studies, playrooms, etc.

Heating mat
Underfloor heating mat set consists of all necessary parts for installation. One Thermostat is needed for every 23 m² of heating mat. It is included as optional, to allow ordering mat for custom areas, for example if you need 13 m² of mat total, you should buy 10 m² with one of the thermostats set as include and 3 m² with thermostat not included. In case you require less mat coverage than possible to buy from our product pictures, for example 14.5 m² you should always round low with your purchase and buy 14 m² as the mat is impossible to cut. It can be shaped but not shortened to size.

Tanking Liquid

Tanking liquid
The tanking liquid is a ready to use, single component, solvent-free sealant mass, consisting of polymer dispersion, fillers and additives. When applied to a substrate and cured, it forms a flexible waterproofing coating. The product is intended for use inside places intended for human residence, especially in humid areas (such as bathrooms, kitchens, laundries), to perform insulation against moisture under linings and coverings, such as ceramic tiles, glazed tiles, terracotta, wooden floors and panels, and synthetic carpets.


The product is intended for priming absorbent and porous surfaces, inside and outside buildings. It is especially recommended for cement - limestone plaster, gas concrete, plaster-carton boards and cement plaster. The primer has a high penetration ability, is deeply absorbed into the substrate, thus strengthening it, while allowing for „breathing”. These benefits improve the structure of the substrates, which, due to the passage of time, have lost their appropriate parameters. The priming solution improves adhesion to the surface of other materials that will be used on the primed substrate. By reducing the absorbency of the substrate, the wear of the applied coating materials, emulsion paints, glues, mineral putties reduces as well. The solution, due to the content of the biocide and fungicide, protects the primed substrate against the formation of mold and bacteria in the product.

Premium Drain

Integrated drain
Shower trays incorporate linear drain built-into the tray during the manufacturing process. Wiper Premium range linear shower drains are made from one piece of 304 grade stainless steel. Only the ends are welded. This means that the flange and drain body are made from the same piece of steel ensuring complete security from water penetration. Our flange is on all four sides of the drain. You will not find a better linear drain on the market.

Our wet room kits are available in three thicknesses: 20, 28 and 35 mm. Depending on space, floor type, and desired gradient you can choose best option for you.

If you have timber floor - existing floor board thickness. Usually they are 20 or 28 mm thick, in that case you should go for adequate thick wet room kit, to avoid floor height increase and step ups. If you want to achieve stepped up floor, 35 mm thickness might also be a good choice. If case of concrete floor, every thickness is suitable, if you're going to screed the floor you need to shutter the future shower area off and leave proper space for tray to be inserted in the future. If screed has already been done, you will need to use jackhammer or similar tool to groove exact tray thickness and shape when the shower is going to be created. In case of both floor types, every shower tray thickness is enough to bear human weight, as it needs to be underboarded beneath entire surface either with ply or solid concrete. The biggest difference between thicknesses is the slope's angle achieved after installation is completed and shower tray tiled.

Is the siphon trap and drain included with the wet-room-kit-800-x-1200-line-sirocco?

Dear Jim,

I would like to confirm that suitable McAlpine siphon trap with pipe is included to this wet room kit. It is completely rotatable and it's pipe height can be adjusted so it gives flexibility to avoid the joists. It features flow rate of 26 l/min and water seal of 20 mm which prevents the air from getting back into the shower.

For the price visible on the product page you receive:

- XPS foam base with pre-machined fall from every corner of the tray to every corner of the drain, reinforced with fibre glass mesh and cement based glue,

- integrated and waterproofed stainless steel channel,

- grating pattern (6 available) - no impact on price nor on performance,

- McAlpine siphon trap with pipe,

Optionally you can include the waterproofing kit to your order, which is very useful especially for timber floor but also recommended for concrete floor.

Can the linear drain be lift up for cleaning the hair etc?

Dear Customer,

I can confirm that the grating can be lifted up after installation is over, to access the siphon trap from above for cleaning. It can be simply opened and standard bathroom cleaning detergents can be used.

I purchased your pure linear drain shower tray last year and I am only getting round to installing it now. I will have to bring the level up with backer board to get the tile up to the drain. What is best practice for applying the backer boards over ...

Dear Customer,

Tile backer boards need to have proper thickness. Distance from the shower tray surface to the top edge of the vertical frame of integrated drain is fixed, 15 mm, so is the maximum thickness for all your material that is going to be fitted on top of it. If your tiles are for example 8 mm, then 6 mm tile backer board should be used and 1 mm layer of tile adhesive.

Boards need to be cut diagonally, to match the angle of the premachined slopes on top of the shower tray. Backer boards can be stuck to the shower tray with tile adhesive, as the tray is covered with material that connects to tile adhesive well on both sides.

Hope that helps, if you have any questions I will be happy to assist.

David 020 7193 0953

Can shower tray be made measure?

Dear Customer,

I can confirm that we can create custom shower tray made to size, it would cost more and we would need more time to deliver (6 business days) but yes, we can basically create any shower tray which is smaller than 2000 mm x 1200 mm. It will probably cost more approximately £50 more than standard shower tray of similar specification.

Please send us dimensions, thickness, drain position, it's style and if you require any waterproofing kit to our email: shop@wetroomsdesign.co.uk. I will prepare proper technical diagram, quote and will reply with all the necessary details.

I am happy to help in case of any questions.

Basically after buying them you will receive everything you need: 900 x 1700 premachined board (falls from every corner of the tray to every corner of the drain) integrated stainless steel channel, grating pattern (6 available) and suitable McAlpine waste siphon trap. 

In addition, you can choose to include the waterproofing kit. Each kit increases the price by £59, so if you went for 6m2˛, it would cost additional £118 total. With the waterproofing kit, you have everything you need to fit the wet room kit and seal it, after doing this it's ready for tiling.

If you have any questions I will be happy to help.

Are your Showerlay Wiper shower trays suitable for a Vinyl Floor finish?

Dear Customer,

Only Showerlay Wiper Invisible are suitable for vinyl floor covering. Other shower trays have vertical frame of 15 mm, so you would need to accomodate that space (best with tile backer boards) to bring it to the frame level, so vinyl sheet is flushed with the drain. If you are able to do this, then you can use any Showerlay, if not, only Showerlays with Invisible drain will be suitable for you.

Peter 020 7193 5485

Is it necessary use tanking kit to install this tray?

Dear Simon,

The Showerlay comes with already integrated and waterproofed 500 mm long stainless steel channel drain. Shower tray itself doesn't require additional waterproofing, however we always recommend to do this, especially for timber flooring. Floor/wall joints as well as the splash area should be protected against water and that's where the tanking kit comes really handy.

Waterproofing kit which can be included to this product, is very efficient, one kit covers 3.2 square metres, contains 4kg tanking liquid, 1l primer, 10m sealing tape, 2 corners and 2 pipe collars. It can be purchased for £59 each, while normal price is £99.

If you have any questions I will be happy to help.

Adam 017 0927 3601

What shower tray thickness should I choose for my timber floor wet room? Do I also need tile backer boards to level up rest of the floor? Can I buy them in your store? Thanks

Dear Ryan,

There are 3 thicknesses available: 20, 28 and 35 mm and they state how thick shower tray is on the edges. They are much shallower near the drain, which is a result of having premachined diagonal slopes towards the drain.

Floor boards are usually 20 mm thick and to install the shower tray you need to remove them to expose the joists, create battons, fix them to the joists and then mount at least 18 mm thick marine ply between the joists. This will create solid even support for wet room kit, which requires to be underboarded beneath entire surface. 

By doing this, you will actually replace the floor board with tile backer board and this will allow to avoid total floor height increase.

Alternatively you can lay the shower tray straight on top of the floor boards but you will need to use tile backer boards to bring up rest of the floor height to the shower tray level.

You can find range of tile backer boards here.

Peter 020 7193 5485

Hi, can I trim this tray to the smaller size? I require 1120 mm x 820 mm in my wet room.

Dear Customer,

Our wet room kits are based on XPS material, which is flexible and can be safely trimmed. This can be done with a regular handsaw, is very easy and does not do any damage to the shower tray.

There's one recommendation from us, if you want to cut for example 100 mm off each dimension, you would need to take equal bits off each side 50 mm from the top and 50 from the bottom as it has premachined slopes towards the drain which need to be preserved.

800 x 1200 shower tray can be shortened down to a minimum size of 600 x 1000 mm.

If you have any questions I will be happy to help.

Adam 017 0927 3601

Hi Do you need a utube in the gulley waste pipe

Dear Customer,

Do you mean u-bend tube?

No, you don't need to buy anything separately, we include McAlpine waste trap with water seal of 20 or 50 mm height and that' enough to prevent the smells from getting back to the shower.

If you have any questions I will be happy to help.

David 020 7193 0953

what size tanking kit would I need for tongue and groove flooring for a 1200X800 tray and which thicknes tray?

Dear Customer,

It depends on your total shower area. Is 800 x 1200 total size of the floor in your shower or is it extended by drying area? If not, one waterproofing kit will be more than enough. Each waterproofing kit covers 3.2 square metres with 2 layers.

Wet room kit comes with drain already integrated and waterproofed so main points of concern are floor/wall joints. The kit is the best for this as it contains 10m sealing tape, 2 corners and 2 pipe collars. If you can spare the tanking liquid, extra waterproofing is always good and should be used to protect the shower area and splash area (extends the shower area by 500 mm off each edge).

We have 30 days unconditional returns right policy so you might want to buy additional kit and if you don't use it you can send it back to us for a full refund.

If you have any questions I will be happy to help.

David 020 7193 0953

hello can we purchase just the the infill piece of the kit?

Dear Customer,

While the grates themselves are not available on our website to purchase, we can supply and sell them. There's 500 mm long linear drain integrated with this shower tray and the grates are interchangeable, so you can purchase any of 6 available grates for this shower tray.

Please call us 020 7193 0953 Mon-Fri 8am-5pm to arrange payment and place the order.


Is the inset drain able to be tiled?

Dear Customer,

Pure grating pattern is designed to be filled with tiles indeed. It features of 12 mm deep channel, so if you're tiles are not thicker than that, this product will be suitable for you. At the end of the day there's only grap between the grating and rest of the floor visible, so that's very minimalistic design.

If you're tiles are thicker than 12 mm you should go for Showerlay Wiper 800 x 1200 mm Line Invisible. It doesn't have any vertical frame, so there's no requirement for finish material thickness. You will need to aesthetically cut the tiles probably with water jet to avoid sharp edges.

Adam 020 7193 0953

What clearance is needed from the end to the floor joist? I see 150mm on the plan but is more needed due to the trap?

Dear Customer,

Distance from the shower tray's top edge to the top edge of the drain is 150 mm and 192 mm to the centre of the waste trap.

You will need approximately 65 mm of height below the shower tray, it's diameter is approximately 8 cm. It is completely rotatable and it's pipe can be adjusted.

If you have any questions I will be happy to help.

David 020 7193 0953

what determines thickness selected 20,28 or 35 mm?

Dear Customer,

Biggest difference between thicknesses of the board is the slope the shower tray provides. Thicker shower tray provides sharper slope. This might prevent water from pooling if plenty of water will be going through the shower, although even 20 mm thick tray provides sufficient gradient to make water flow towards the drain. As the bottleneck of the flow rate is the waste siphon trap and we include exactly the same to any thickness it does not determine maximum capacity of the shower tray which is always 26 l/min.

For timber flooring 20 mm thick tray is recommended, because floor boards usually are 18 mm thick and by proper installation you can avoid increasing rest of the floor height. If you have much space you can go for thicker tray if you prefer to have steeper shower.

20 mm thick trays are the most popular one, therefore we carry largest amount of them in our warehouse for next day delivery. Some of 35 mm thick trays might be available within 3 business days.

If you have any questions I will be happy to help.

What are the dimensions of the cutout for drain on the Showerlay Wiper 800 x 1500 mm Line Pure?

Dear Customer,

800 x 1500 shower tray can be trimmed to a minimum size of 640 x 1300 mm.

There's a recommendation though - it would be the best if you could cut equal bits from each side to make sure to keep premachined slope. For example, if you want to shorten 1500 dimension to 1400 it would be the best if you took 50 mm from the top and 50 mm from the bottom of the shower tray.

If you have any questions I will be happy to help.

can the 20mm board be used to replace floorboards in a bathroom with standard 400mm joist centres thanks

Dear Customer,

20 mm thick shower tray is the best for timber floor type. Because floorboards usually are 20 mm thick, 20 mm thick shower tray should be a good solution. According to our fitting recommendations, you need to:

1. Remove floor boards to expose the joists,

2. Prepare and fix battons to the joists, approximately 20 mm from their, upper level.

3. Mount at least 18 mm thick marine ply between the joists, on top of the battons.

4. By doing this, marine ply should be the same level the joists are and this should be a solid support for the shower tray.

5. Shower tray can be fixed using tile adhesive.

If you have any questions I will be happy to help.

Kind regards,

what colour is wetroom tray?

Dear Customer,

Colour of wet room kit is between grey and brown, because it's reinforced with cement. Please notice that shower tray needs to be covered with floor finish material like tiles or mosaic, so you only part of the unit visible after installation is done is the stainless steel drain part. It's not a ceramic shower tray, it's floor level walk in shower tray.

If you have any questions I will be happy to assist.

We'd like to use this slot drain in a 1100 wide x 800 deep alcove, with 600 x 600 tiles. I assume we need to make tiles to either side slope slightly? what do you recommend. thanks Jeremy

Dear Jeremy,

If you have 800 x 1100 mm of space, it might be better to go for 800 x 1200 wet room tray with drain already integrated and slope premachined from every corner of the board to every corner of the drain. It's a very delicate slope yet sufficient for effective water flow.

Shower trays can be cut to avoid obstacles or trimmed down to size, 1200 mm side can be easily cut to 1100 mm with a standard handsaw.

In case you prefer to use a linear drain - that's also possible, however you would need to put an effort to prepare the slope on your own.

If you have any questions I will be happy to help.

I intend to order a Showerlay Wiper 1000 x 1000 mm Line Pure (plus kit) next Tuesday. I am awaiting the plumber's decision as to the thickness required. If I order the tray by midday on Tuesday, will you be able to get it to me on Wednesday?

Dear Customer,

I can confirm that this product is available with next day delivery, therefore if you order it on Tuesday before 3 o'clock, we will ship it same day and it will be delivered on Wednesday.

Regarding thicknesses - basically biggest difference between each thickness is the slope - thicker shower tray is steeper. For timber flooring, we recommend 20 mm thick board, as the floor boards usually are 20 mm thick, and by fitting shower tray of the same thickness you can avoid increasing total height of the rest of the floor.

I am happy to assist if you have any questions.

Kind regards

Can the former sit on the joists or does it sit on the flooring

Dear Customer,

Our Showerlay must be fully underboarded, but by proper installation you can achieve the same way as if it was sitting on the floor boards. Basically you need to remove existing floor boards to expose the joists. Then you need to prepare battens and fix them to the sides of the joists. After it's done, you would need to mount at least 18 mm thick marine ply between the joists, on top of the battens. By doing this you will be able to replace former floor boards with the shower tray.

Please see our fitting instructions for more details.

I am happy to help if you have any questions.

Kind regards
