The short answer
A full mobility bathroom conversion in the UK typically costs around £4,000–£8,000, with more involved projects — structural changes, wider doorways, premium finishes or extensive adaptation — reaching £10,000 or more. A complete conversion usually replaces the bath with a level-access shower or walk-in bath, adds grab rails, a shower seat, anti-slip flooring and an accessible basin and toilet, and makes the room safer to move around. Much of the cost can be met by the Disabled Facilities Grant (up to £30,000 in England) following an occupational therapy assessment, and the disability-related elements are usually zero-rated for VAT. As with any adaptation, the right figure depends on the person's needs and the room.
A full conversion turns a standard bathroom into one designed around the user's mobility. Because the scope is wider than a single fixture, the cost spans a broad range. Here is what it typically includes and costs.

How funding reduces the bill
Because a full conversion sits squarely within what the Disabled Facilities Grant is designed to fund, many households pay considerably less than the headline figure. The grant covers up to £30,000 of adaptations in England following an OT assessment, and the disability-related parts of the work are usually zero-rated for VAT. It is worth starting the grant conversation with your council early, since the assessment and approval can take time. The grants page sets out the route in full.
