Levelling and tiling en-suite floor with Mapei Ultraplan Renovation
Hi all,
I'm an enthusiastic DIY'er (first time poster) who has been slowly chipping away at an en-suite bathroom renovation for a few months. Last night I went to install the shower tray (1600 x 900) and I realised that the floor by the drain end was about 10mm higher than the floor at the other end. This slope continues across the whole room. I've concluded that the best solution to this problem is to use some self levelling compound as not only will this level the shower tray but it should help get a better finish on the floor which is being tiled with 1200mm wood plank porcelain tiles.
As you can see in the photo, the floor is 22mm chipboard which is glued down in the older parts and screwed where I have replaced some boards. I've measured about 20 places across the floor using a laser level and I think the worst dip is about 13mm by the door. It also looks like a previous owner has already used some kind of leveller in the central part of the floor.
I just wanted to run my plan past some more experienced bathroom installers to get confidence that I am heading in the right direction before diving in.
Assuming that all sounds reasonably sane I then had some follow up questions:
Any thoughts/tips/advice very welcome. Thanks!

- Trim back the plasterboard/tile board where it meets the floor to ensure decent clearance from the raised floor level (where needed).
- Briefly sand the floor with a course grit and hoover.
- Wash the floor.
- Fill the joints in the chipboard (and a couple of old screw holes from the old toilet with silicon)
- Use silicon to seal between the wooden/metal sole plates and the floor on internal walls.
- Use expanding foam to seal the gaps between wall and floor on external walls.
- Use expanding foam to create a dam around the shower waste hole.
- Prime the floor with Eco prime grip plus.
- Level the floor with Ultraplan renovation.
- Trim back the excess foam and marvel at my smooth, level floor.
Assuming that all sounds reasonably sane I then had some follow up questions:
- Can I tile directly onto the ultraplan renovation or does it need cleaning/priming again?
- I originally planned to overboard the chipboard with some tile backer board but if the floor is already level/stable this seems like it might be redundant now. The ever increasing height of the floor is also a challenge.
- I saw something in the instructions about minimum depth over wood should be 3mm. Does this mean I need to go 3mm past my highest point even though the room is already theoretically level at that point? Seems like a waste of material and unnecessary extra height on the floor.
Any thoughts/tips/advice very welcome. Thanks!
