Any Ideas

[cr0ft]

Hi all,

We're fitting a bathroom in a very old property and the floor slopes off by about 1.5cm from one end of the bath to another. Normally in these circumstances I would recommend a wooden or tiled bath panel that can be neatly cut. This time though it's a P-Shaped shower bath so a plastic panel seems the only option. Tiling to sort out the difference in level isn't an option as the existing joists are too springy to fit a tiled floor to.

Any ideas how we can hide a gap around the bottom of the bath panel? My thought was some thin white PVC trim cut into 2 straight bits and a curved bit. Glue them all to the bottom of the panel and jobs a good one. Any better ideas?

Can you not cut angled packers to back the boards up off the joists,
A bit time consuming but you'll have a nice level floor

I once had to get a wet room floor to slope the opposite direction to which it was already in a grade 2 listed.

Got a wood butcher in and he trimmed down some CLS to level and create a slope which we then fixed 18mm ply to. The splices were 2mm thick at one end and 20-25 at the other fixed over rough oak joists with no void. Took a day to do just that job but the outcome was sooo good and satisfying I'd do it again rather then mess about trying to get around it after it was too late

I would tend to go the who;e hog as above, fix the springy joists, cut in some furrings to level it out and nice ply floor to work on, saves on call backs in 6 months time.

Employ a chippie if need be, pack out the joists and get the floor level.

Don't you guys have a floor leveling compound?

Mix it up in a bucket and pour it out - self leveling.

That'll take up the first 6mm

Some of their products can do up to 25mm, any thicker they want you to add aggregate.

It's a timber floor on the first floor of a building, would that work?

not on floorboards

It's WBP Plywood but as the joists are pretty springy too I would be concerned about it cracking over time.

I'm so glad I don't do many bathrooms they are just a pain in the rear.

If it was me I would want to have the lot sorted by getting a chippy in, it will cost more now but it would mean the bathroom would last longer and the last thing you want is the bath to drop a bit and let water in causing damage.

We do has self levelling but its only recommended for solid floors not timber as it'll just crack

I'd take the floor boards up, sort the joists out by screwing 8x1 to the side of the existing joists and then relay the floor with sheet , ideally ply or green chipboard feeling tight!

Seen this done a lot and strengthens the joists somewhat as well. Hardest part is hitting the 1" when screwing the floor down!
