I need showers for 50 construction workers with limited power. What are my options?
A modular solution can be sized with a tailored mix of P300, P400, P500, P600 and P700 units, then fitted around the intended use. The online designer shows the final calculated total for the exact configuration before a formal quotation.
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
- Hire avoids purchasing the building outright
- 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
Hire suits a short programme and avoids the capital outlay; on a long one, buying may give better overall value and the block can move to the next site. Adacon can price both. Get the incoming supply measured first — it decides the heat source and therefore the layout.
What each size gives you
Mix P300, P400, P500, P600 and P700 units around the space needed; the designer calculates the final total for the exact result.
| Modules | What it gives you |
|---|---|
| 2 modules | Around 4 showers and a small changing area |
| 3 modules | 6 showers, changing benches and WCs |
| 4 modules | 8 showers, separate WCs, drying and changing space |
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
P300–P700 range, or bespoke
- P300 unit
- 2.9m × 2.2m externally; approximately 2.7m × 2.0m usable internally (5.4 m² usable internal area per separate unit)
- P400 unit
- 3.9m × 2.2m externally; approximately 3.7m × 2.0m usable internally (7.4 m² usable internal area per separate unit)
- P500 unit
- 4.9m × 2.2m externally; approximately 4.7m × 2.0m usable internally (9.4 m² usable internal area per separate unit)
- P600 unit
- 5.9m × 2.2m externally; approximately 5.7m × 2.0m usable internally (11.4 m² usable internal area per separate unit)
- P700 unit
- 6.9m × 2.2m externally; approximately 6.7m × 2.0m usable internally (13.4 m² usable internal area per separate unit)
- Configuration
- Mix P300, P400, P500, P600 and P700 units to create tailored footprints and shapes
- Bespoke
- Bespoke sizes considered to suit your brief — contact us
- Joined internal space
- Open joins remove the adjoining shell walls and can increase usable space. Final clear area depends on layout and partitions.
- Unit height
- 2.40m external / 2.16m internal
- Storeys
- Up to two storeys, subject to final project design
- Delivery
- UK mainland and Northern Ireland — transport quoted separately
Adacon modular buildings use P300, P400, P500, P600 and P700 units with external lengths of 2.9m, 3.9m, 4.9m, 5.9m and 6.9m, a common 2.2m width and 2.40m external / 2.16m internal height. The sizes can be combined to create more tailored floor areas and building shapes, joined side by side or stacked to two storeys subject to the final project design.
