Planning an en-suite bathroom
Adding an en-suite usually means extending plumbing and sometimes electrical circuits into a new area, and ventilation (an extractor fan, by regulation) becomes more important in a smaller enclosed space. Worth planning the layout around existing pipe runs where possible to control cost.
What affects the cost
Cost depends on whether pipework and electrics need moving (not just swapping fixtures in place), the tiling area, fixture quality, and whether structural changes are needed (like removing a bath for a walk-in shower). Moving a toilet's position, in particular, is one of the more expensive changes because of the soil pipe work involved.
Bathroom flooring options
Vinyl flooring is cheap, waterproof and easy to fit, suited to budget refits. Porcelain tile is more durable and higher-end but needs a sound, flat subfloor. Underfloor heating compatibility and slip resistance (particularly around a shower) are worth discussing alongside the look you want.
Bathroom regulations, FAQ
Do I need building control sign-off for a bathroom refit? Usually not for a like-for-like refit, but new electrical circuits or moving significant plumbing may need it, handled via the relevant registered tradesperson. Can I do my own tiling? Yes, tiling itself isn't regulated — it's the electrics and plumbing behind it that are.
Planning bathroom storage during a refit
Built-in storage (vanity units, recessed cabinets) is far easier to plan during a full refit than to retrofit afterwards, since it often needs coordinating with tiling and plumbing runs. Worth deciding on storage needs before the layout is finalised, not after tiling is complete.
Why bathroom electrics need a registered electrician
UK wiring regulations split a bathroom into zones based on distance from water, restricting what electrical fittings can go where. This makes bathroom electrical work notifiable under Part P — a fitter doing the tiling and plumbing will typically bring in (or should) a registered electrician for any new sockets, extractor fans or lighting circuits.
Why waterproofing (tanking) matters
Tanking is a waterproof membrane applied behind tiles, particularly around showers and baths, to stop water getting into the wall or floor structure below. Skipping this step is a common cause of hidden damp and rot that only becomes visible years later — worth confirming it's included, not assumed, in a refit quote.
Shower screens vs shower curtains
A glass shower screen looks cleaner and is easier to maintain long-term than a curtain, but costs more and needs to be fitted correctly to avoid water escaping at the edges. A curtain is the cheaper, more flexible option, particularly for an over-bath shower.
