Linear drain

Can I install it in wet room tiled floor?

Dear Pamela,

Premium drains are designed to be installed in wet room tiled floors. Please notice that the distance from the stainless steel flange surrounding the drain, integrated for sealing purposes, to the top edge of vertical frame is 15 mm, so is the maximum thickness for your tiles plus adhesive and insulation. 8 - 12 mm is the optimal tile thickness for this drain type.

Please notice that you need to create your own slope in your shower to make sure water is not pooling on the floor and we recommend to have at least 150 mm from left, right and upper drain edge to the walls. Alternatively if you don't want to worry about this you might take a look at our Showerlay Line wet room kits drain range, with this drain already integrated and waterproofed.

Kind regards,

David

Hi, Can these be installed on a computer floor system? (RAF)

Hello,

I can confirm that those drains are compatible with any floor type installation, where they can be installed flushed with it. That is, concrete, timber and raised access flooring, as long as there is sufficient space under for the waste trap (shallowest one is 46 mm - the Snake trap).

VF drains specifically are designed for vinyl floor coverings, including safety flooring.

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

Kind regards,

Bought shower tray for wet room gully has 50 mm drain hole what do you recommend for a waste drain bearing in mind the channel on the tray you sold me us is narrow

Hello Denis,

Thank you for your question.

We have multiple waste traps compatible with our trays. You ordered the shallowest one with 26 l/min of flow rate.

There are various traps, some of them with greater throughput and water seal but slightly more height.

Let me know what kind of technical property you're interested in and I will reply what't the best option in that case.

Showerlay line

Hello, could you please tell me, how long for delivery showerlay linear 800x1000 £ 299.99 to London NW6. I would need it for Tuesday/Wednesday ne . . .

Dear Katie,

Unfortunately 800 x 1000 is not one of our standard size, we could manufacture custom shower tray, it would be slightly more expensive and we would need few more days to produce and deliver.

Alternatively you might want to buy Showerlay 1000 x 1000 mm Line and then trim it. That's very easily and can be done with regular handsaw, doesn't do any harm to the tray. Only requirement is to trim equal bits off each side to make sure that pre-machined tray is preserved.

As it's one of our standard sizes, it is available off-the-shelf, so if you order it today before noon you will probably receive it tomorrow. Shipping confirmation will be sent just after it's in transit, with tracking details so you will be able to predict it's arrival on your own.

In case you need anything I will be happy to help.

Kind regards,

We have a concrete subfloor, on which we intend to use 75mm insulation where the shower tray will be installed, with liquid screed on top. We can go for 47mm thick screed, which with the 28mm thick tray would bring it to the same height as the 100 . . .

Hello Steve,

Thank you for your question.

You can either install the tray at it's future destination (if that's possible) and screed around or do the shuttering off and screeding. If mounting the tray at appropriate level before screeding is not possible, you should shutter the area off, fill with concrete and then insert the tray, with grooving some space if needed.

The tray is suitable for mosaic floor as long as it's not smaller than 10 mm x 10 mm. Having the small mosaic tiles not aligned perfectly with the slopes of the tray is not an issue, there will still be difference in height of the tray on the edges and near the drain, so water will still flow towards the drain.

I will be happy to answer if you have any questions.

Kind regards

Hi, our bathroom has a concrete floor and will be insulated with 100mm kingsman and then 50mm screed. Would it be best to construct a timber frame etc to site the tray former on before the floor is finished, I.e shutter the tray size within the in . . .

Hello,

Thank you for your question.

There are 2 ways to install the tray, first most common one is to have it installed flushed with rest of the floor. The tray itself doesn't need insulation boards as it is based on XPS which is material providing great insulation itself.

Alternatively you can create a frame that the tray would sit onto. This may be a better solution if you prefer the same insulation under the tray as under rest of the floor. However in this case, you would have a step up, which most people want to avoid.

Many thanks for being interested in our products.

Dear David,

If you want to buy a tray with right-hand side corner, that would need to be a bespoke product.

Square Traps

The traps seem to have compression or screw in joints for the waste pipe. Is it ok for these joints to be embedded in screed ? Do you have traps without screw in joints and that can be solvent welded to the waste pipe ?

Hello Justin,

Thank you for your question.

There's a selection of the traps available in our store, both for linear drains and wet room trays.

They are compression fitting indeed. I have sent a document showing all available traps to your email.

Underfloor Heating

Are your underfloor heating mats secondary or primary output?

The issue is not the underfloor heating, and more the insulation in the property. The mats are 150w/m2 (required for VDE approval) and is reliant on suitable insulation within the property. Insulation beneath the ufh, to ensure maximum heat goes into the room, and then insulation within the room, to ensure the heat remains in the room. In new properties, there is no issue, due to insulation standards being extremely high. In older properties, where insulation is lacking, is where we forsee an issue. If insulation is up to scratch, there should not be a problem. If the customer is concerned, or want to ensure a suitable output, a heat loss calculation must be carried out.

If you have any other questions I will forward them to the manufacturer and then reply to you.

David 020 7193 0953

Hi there, I'm wanting to use underfloor heating as the main heat source in the room, and have been advised that I may need to increase to 200W per square metre. I notice all your mats are standard 150W. Also because it's an odd shaped room, I woul . . .

Hi Tim,

We do not know any recommendation about the heating mat to be at least 200W per square metre. It depends on many factors like type of the building, insulation etc.

Our mats have been supplied many times for a primary heating source.

We do supply a cable, please have a look: https://wetroomsdesign.co.uk/magnum-underfloor-heating-cable-1941-m#/130,thermostat,not-include/137,spacer-strips,not-include

Hello,

I can confirm that Sunfloor heating mat is compatible with more thermostats than just those of Sunfloor brand.

To confirm if it works with Nest thermostat, you would need to make sure that your specific thermostat is compatible with 150W/m2 electric heating mat.

Accessories

Dear Sirs, we are intresting in 3 meters width waterproofing membrane? Is it possible to produce such? It would be regular 400-500 sq m orders per month. Thank you!

Hello,

Those membranes are only available in 1 or 2 m widths. I can speak to the manufacturer if 3 m version can also be made, however it would be hard to transport and would be significantly more expensive.

Please let us know if 1 or 2 m versions are acceptable and we will prepare a special offer for you because of the wholesale nature of your request.

how long after manufacture can i use it. I've got 2 bags that i purchased from you last august 1 batch number 21/18. and 1 29/18. thanks

Dear Daniel,

Shelf life of the Nanofug Premium is 12 months, therefore as long as it's not been opened it can still be used within several months.

If the bags have been opened they are probably no longer usable and you will need to supply a new product.

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

Showerlays

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.

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.
