Bath to shower conversion cost
Straight answer first: a straight swap is £3,300 and a full conversion is £4,300 with M3 Trades, supply and fit. Below is exactly what sits inside those prices, what genuinely costs extra, and why other quotes come back so different.
The three prices
What you'll pay

Straight swap

Bath removed, waste and feed reworked in the same position, low-profile shower tray, enclosure, thermostatic mixer and tiling to the wet area.
Best for: Most family bathrooms where the layout stays as it is.
Full conversion
£4,300
Everything in a straight swap plus larger walk-in tray or wet-floor former, full-height tiling, new flooring, boxing-in and a replaced basin or WC where needed.

Conversion vs full renovation
If the rest of the room is sound, a conversion is the cheaper route by a distance.
A full bathroom renovation replaces everything — suite, tiling, flooring, sometimes the layout — and typically runs £5,000–£8,000 for a standard refurb, £8,000–£13,000 mid-range. It takes 10–15 working days.
A conversion keeps the basin, WC and most of the room, replacing only the bath area. That's £3,300 to £4,300 and three to five days. If your tiling and suite are tired anyway, the full renovation usually works out better value per pound — we'll tell you honestly which one your bathroom needs.
