hi all,

Newbie on the site but reading through your post has really helped.

A builder is installing an wet room in my new loft conversion. I wanted to know what’s the best system i.e tray and membrane or tray and roll on?

I know about the highly recommended Impey tray and kits but was recommended this as Linear Wet Room Kit | Walk in Shower | 1200 x 900mm | Wetrooms Online - https://www.wetrooms-online.com/wet-rooms/wet-room-kits-trays/wetbase-linear-wet-room-kit/linear-end-drain-wet-room-walk-in-shower-kit-with-tileable-cover-1500-x-900-x-30mm-detail.html by another tiler.

I a worried about leakes and Impey looks like May have issues with drains as far as read.

Looking for a base which is a minimum of 900 x 1200

Any help and advise you be great.

No floor has been laid, so wooden sub floor. Will be think porcelain tiles and money is tight.

Thank you

Think tiles, or thin tiles? :)
If it’s thin tile, cutting corners will not work, money tight or not, do not compromise.

If money is tight you can’t go wrong with Marmox Showerstone. Solid trays and really cheap IMO.

No matter what system is used, if its installed incorrectly it will 100% fail. Either in a couple of weeks or a couple of years.
You said installed by your builder, and while I don't know him, it's true to say that builders and wetrooms always equate to problems in my experience.
Contact the manufacturer and get a recommendation.

has the builder got any references from installing previous wet rooms? I would contact a manufacturer for a recommended tiler or even maybe use the forum find a tiler and get a second opinion? If you have a leak that will potential ruin more than Just the loft floor.

If you have a tight budget a wetroom is probably not the best way really.

Have you considered a normal shower tray, have a look at Just Trays Evolve, they make them as low as 25mm and make them in different colours.
If put directly on the deck by the time you have tiled the rest of the floor it is basically the same height.
