I need showers for 50 construction workers with limited power. What are my options?
Fifty workers typically needs six to eight showers plus changing space, which is three to four joined modules from £32,250–£43,000 + VAT. Where electrical capacity is tight, the practical answer is a stored-water system with a gas or heat-pump heat source rather than multiple instantaneous electric showers.
Electric showers draw heavily and all at once — a shift ending is the worst possible load profile. Sites that try to run six instantaneous showers off a limited supply end up tripping the board or running cold, so the heat source matters more than the block itself.
Your options compared
Modular shower and changing block
Purpose-built joined modules with showers, changing benches and WCs.
- Sized to the workforce and reusable on the next site
- Proper drainage, ventilation and slip-resistant finishes
- Heat source specified around your available supply
- Needs water, drainage and a power connection
- Requires a level standing and delivery access
Hired welfare trailers
Towable units hired by the week.
- Fast to get on site
- No capital outlay
- Hire cost accumulates across a long programme
- Limited shower numbers per unit for a 50-strong crew
- Nothing to show at the end
Existing building conversion
Fitting showers into an existing structure on site.
- No new building
- Drainage rarely exists where you need it
- Wet works and programme risk inside a live site
On any programme longer than a few months, a bought shower block beats accumulating hire charges and can be moved to the next site. Get the incoming supply measured first — it decides the heat source and therefore the layout.

How to get it moving
- Confirm your available electrical capacity in amps, and whether gas is available
- Confirm where foul drainage can be connected
- Decide shower numbers against shift patterns, not headcount alone
- Design the block in the builder and get a written quote
- Agree the standing, access route and offload method
Costs on top of the building
- •VAT at the prevailing rate
- •A level, load-bearing base or foundation sized to the building
- •Transport to site, quoted on distance and access
- •Offloading, and crane or hiab attendance where access requires it
- •Final connection to mains power, water and drainage by your own contractor
- •Planning permission or building control fees where these apply
