A complete mobility bathroom commonly takes longer than a simple replacement shower because access, drainage, waterproofing and support fittings all have to work as one system. The exact programme depends on the room. A careful installer should give a realistic sequence after the survey rather than promise the same number of days for every home.
What are the main stages?
- Protection and removal: floors and the access route are protected, then the old bath, shower, sanitaryware and finishes are removed.
- Opening-up inspection: hidden pipework, floor condition and walls are checked once exposed.
- First-fix work: water, waste, electrical and ventilation routes are altered.
- Floor and wall preparation: the former or tray is set, reinforcement is installed for rails or seats, and surfaces are made sound.
- Waterproofing and finishes: tanking, wall panels or tiles and safety flooring are installed with the correct curing times.
- Second fix: the shower, WC, basin, screens, seat, rails and accessories are fitted.
- Testing and handover: water flow, drainage, controls, seals, electrics and ventilation are checked and explained.
What can make the programme longer?
- Lowering drainage for a level-access shower.
- Repairing rotten timber, cracked substrates or previous leaks.
- Replacing unsuitable old pipework.
- Electrical upgrades or a new extractor route.
- Drying and curing times for screeds, tanking, adhesives and sealants.
- Bespoke screens, furniture or non-standard products.
- Suspected asbestos-containing materials in an older property.
HSE states that asbestos can be present in buildings built or refurbished before 2000. If suspect material is found, work should stop in that area until it is assessed. See HSE asbestos guidance.
Can the toilet remain usable?
Often the WC can be reconnected temporarily or replaced in a sequence that reduces disruption, but this depends on the layout and drainage work. Tell the surveyor if the property has no second toilet or if the customer cannot use another floor. The installation plan can then address this before work starts.
How can delays be reduced?
- Complete a detailed survey rather than relying on rough measurements.
- Agree the specification, colours and accessories before ordering.
- Confirm product availability before fixing the start date.
- Record drainage and electrical assumptions in the quotation.
- Plan access, parking and waste removal.
- Tell the installer about known leaks, weak floors or previous alterations.
A fast installation is useful only when the hidden work is allowed enough time. Waterproofing and sealants should not be covered or used before the required cure.
What should the quotation tell you?
The quotation should describe the scope, not just the visible products. Look for removal, waste alterations, wall and floor preparation, tanking, finishes, electrical or ventilation work, disposal, testing and making-good. It should also explain how unforeseen defects will be handled.
Government guidance notes that bathroom plumbing and electrical changes may need Building Regulations approval or competent-person certification. Read GOV.UK’s overview.
Frequently asked questions
Can I stay at home during the work?
Usually, yes. Expect noise, dust and periods without bathroom facilities. If the customer is medically vulnerable or has only one WC, discuss the daily plan in advance.
Can a bath-to-shower change be quicker than a full bathroom?
It often can, provided the surrounding room, drainage and services are suitable. A full conversion includes more first-fix and finishing work.
Why can the start date be later than the survey?
The final design must be agreed and products ordered. Bespoke screens or specialist accessible equipment can have longer lead times.
