In Sunbury-on-Thames we cover KT12, TW16 and TW17; we also cover Walton-on-Thames, 1.2 miles away, and West Molesey.
In Sunbury-on-Thames, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If you have young children at home in Sunbury-on-Thames, we can talk through a bath that is easy to lean over, a slip-resistant floor and high-level storage. For a busy Sunbury-on-Thames household sharing one main bathroom, a thermostatic shower over a full-size bath is usually the most practical layout.
Most of Surrey has hard water. We plan easy-clean glass, rimless toilets and finishes that do not show limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Strip-out of the old suite and tiles, with the waste taken away by a licensed waste carrier
- Final silicone, a test of every tap and waste, and a clean handover
- Wall and floor tiling, with a floor finish chosen to grip under wet feet
- New pipework, wastes and isolation valves, plus a thermostatic shower valve so the temperature holds when someone runs a tap
Decisions to make first
Floor
Matt or textured porcelain is the hardest-wearing option. Luxury vinyl tile (LVT) is warmer, quieter and cheaper to lay. Avoid polished tiles where children climb out of the bath.
Bath material
Reinforced acrylic is warm to the touch and light on the floor. Steel enamel is harder-wearing and feels more solid, but it draws heat from the water faster.
Rules that apply in England
In England, any new circuit, or any change to the wiring in a room with a bath or shower, is notifiable under Part P. Part G limits the hot water at a new bath to 48 °C only in a new dwelling or one created by change of use; it does not apply to a replacement bath in an existing house, but a thermostatic valve is a sensible choice where children bathe.
