I have ordered the rubber flooring for the playroom. 3mm thick black rubber, round 'penny' design (I thought it easier to mop up fluids from this design rather than the 'checkerplate' design). It comes in 1.5m wide strips.
Measuring the floor area, ignoring the shower, the floor measures 272cm x 338cm.
Allowing for the rubber to run up the skirting boards too, I'll add 10cm all round, so that's 292cm x 358cm.
I have ordered two strips, 150cm wide by 400cm long, so fitted side-by-side, that gives up to 300cm x 400cm - perfect.
The floor is currently bare floorboards, so my plan is to screw sheets of 3mm waterproof plywood down over the boards to give a smooth surface and a layer of noise attenuation, then glue the rubber into place on the plywood.
The whole idea is to protect the lounge below from play involving body fluids, and make any clean-up easier.
I'll fit the rubber floor down first, all round the room into all the corners and up the skirtings, then the shower tray can sit on it in the corner and get plumbed in when the bathroom gets replaced soon.
