What does a new bathroom design cost in Sevenoaks?
Design comes with the job: the survey, layout and itemised quote are free. In Sevenoaks, a complete designed, supplied and fitted bathroom typically costs £7,300–£13,500 including VAT. Prices in South East England run at about 12% above the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Sevenoaks
In Sevenoaks we cover TN13; we also cover Tonbridge, 6.5 miles away, and Swanley.
Homes in and around Sevenoaks vary, so we look at the floor, the walls and the water system before we price anything. For loft rooms and sloping ceilings in Sevenoaks homes, the design checks head height where you stand, not just the floor area. We measure Sevenoaks bathrooms on site before drawing anything, so layouts are based on your walls rather than a standard plan.
Water across much of Kent is very hard. 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
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
- A lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
- A product list covering the suite, brassware, furniture, tiles, lighting and ventilation
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
Decisions to make first
Storage
Fitted furniture, a vanity with a tall cupboard, or recessed niches and a mirror cabinet. Recessed storage costs no floor space but needs a stud wall or deep boxing to sit in.
Planning for later
Timber noggins in the walls for future grab rails, a wider door or a level shower floor cost far less to build in now than to add later.
Rules that apply in England
In England, a new connection to the soil stack or new drainage can be building regulations work under Part H, and new circuits or alterations to circuits in the bathroom are notifiable under Part P. Where a new bathroom is formed, Approved Document F asks for extract at 15 l/s intermittent or 8 l/s continuous.
