A bathroom is mostly a question of where the water can go, and in Bedworth the answer depends on whether the front of the house is protected.
On modern housing the soil stack is internal and a bathroom can be moved easily. On the older terraces it runs on an outside wall, and in Bermuda or a conservation area, where an Article 4 direction may apply, altering a street facing elevation becomes a conversation with the borough rather than a decision on site. Behind the building line there is far more freedom, which is where most relocated bathrooms end up.
Floors are the second constraint. Older upstairs joists were sized for a bedroom, not for a filled bath on a tiled floor. Where a waste run means notching or drilling them there are permitted zones, and the wrong cut in the wrong place is common and serious. We will move a fitting a foot rather than cut a joist where it must not be cut.
Ventilation gets treated as an afterthought and causes years of trouble. An extractor discharging into a roof void puts moisture straight back into the building, and in an older roof it finds the timber. We duct it outside.
Tanking is not optional on a walk in shower, because tiles and grout are not a waterproof layer. Our bathroom installations page sets out what a full refit involves.
