Not sure whether to buy a 30 or 40mm thickness tray. Is it dependent on the structure of my floor? Many thanks, Andy

Dear Andy,

Thicker tray provides better slopes and insulation but requires more space and costs more.

You need to decide what's better for you.

20 mm is the most popular thickness and offers sufficient slope for most Customers.

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

Kind regards
