Bathroom tiling for Longlevens' inter-war semis
Longlevens is largely 1930s semi-detached housing, built with solid or early cavity walls and small original bathrooms. Tiling in these rooms usually means dealing with an uneven original plaster finish rather than a flat modern board substrate.
Your questions answered
Can large-format tiles go straight onto old plaster?
Not reliably, an uneven or soft original finish should be battened or boarded first so the tiles don't crack along hollow spots.
Is underfloor heating an option under tiles in these houses?
Electric mat systems can usually be added under tiles on a solid ground floor without raising floor levels significantly.
Technical considerations
Point 1
Original 1930s wall plaster is often slightly bowed, so a levelling coat or backer board is usually needed before large-format tiles will sit flat.
Point 2
Small original bathroom footprints mean tile layout has to work around a single external wall window, limiting where full-height runs can start.
Point 3
Solid ground floor slabs in these semis are generally sound for floor tiling, though older concrete may need a damp check before tanking.
