Shower Tray queation

[Too Late]

We are currently looking to purchase a shower tray for an ensuite. Having just measured the walls (not tiled) they are 990mm.

What am I best to do here. Showers trays come in 1000mm or 900mm.

I could of course notch 5mm on the left and right side of the wall. Or get a much smaller tray.

I could plane the studs back by 5mm

What do people think is the best option

If you are confident with your measurements, I would notch 5mm off either side. 90mm is a lot to 'pad' out.

Just my 2p, though.

Will the enclosure still fit if you set the tray into the wall too far

Are the walls boarded yet, that will add 8/10/12mm at one or botch sides of the tray

Composite trays can be cut using a tile disc in an angle grinder… I’ve trimmed 25mm off the length of a 750mm wide tray before so it perfectly fitted a recess.

Obviously not an option with a plastic tray.

Are the walls plasterboard or cement board?

OTOH, 90mm might be a 45mm tiled ledge at each side, or less than that once you've got 10mm of tiles on the wall.
With backing boards or other wallboard solutions for showers, it's easy to lose 90mm.

My ensuite was 1270mm wide between plasterboard walls.

I didn't want to use a short shower tray due to the difficulty of making it watertight.

I chopped back the plasterboard and cut back some studwork and I managed to fit a 1300mm shower tray.

It was very difficult dropping the shower tray into place on top of a bed of sand and cement.

The shower panel walls now overlap the edge of the tray and hopefully watertight,

Hi all,
The walls are already boarded out, so I only need to shave off around 10mm in total (5mm each side) to get the tray in.

My idea was to plane back the studs slightly so I can still fit the cement boards behind the sides of the shower tray, ensuring it can be waterproofed as effectively as possible.

Some makes of trays are smaller than they say, so physically check the tray you are getting.

[Drumroll]

I would go the other way gat the smaller one and "pad it out" You don't know how much strength you will loose by cutting back on the tray.

The cement boards would work as well / if not better if overlapped on to the tray at one or both ends, you can then seal / stick them to the top of the tray.

Simply cut the stud back. I removed the plaster board and used tile backer board and used a sealant (tanking kit) so everything was totally waterproof.

Definitely get a 1000 , it will probably be 995 anyway . I guarantee getting a 900 and making up the difference will not go well

Is the current boarding plasterboard and skim? If so a 6mm cement board in its place could give you the extra mms.

6mm might need some extra studwork behind depending how far apart your studs are.

Cement board is not waterproof, just saying...
Use the 1000 one, a step at one or both ends WILL leak.
