Wet room conversions in Hucclecote's inter-war and post-war semis
At a glance
- Suspended timber floors need a pre-formed fall unit let into the joists, which requires checking joist depth and span before ordering.
- Upstairs wet rooms in these semis add weight and standing water risk, so waterproofing continuity between floor and wall junctions is critical.
Your questions answered
Can an upstairs bathroom in a 1930s semi become a wet room?
Yes, but the floor structure needs assessing to fit a shallow former without excessive notching of the joists.
Is a rear extension a better place for a wet room?
Often, if it has a solid floor, it avoids the joist and headroom constraints of an upstairs timber floor conversion.
