Our story
A Norfolk family business, solving a simple problem
Nobody should have to rely on a relative's bathroom for six weeks while their own is being replaced. WashBox provides a straightforward alternative.
Meet the founder
Lee Emmerson
I have spent years in people's houses fitting bathrooms and heating, and kept hearing the same thing: "where are we supposed to wash while you're doing this?" Families were using relatives showers, paying for hotel rooms or putting up with a plastic toilet in the garden. None of it was good enough.
So I built the thing I'd want on my own drive — a shower, toilet and basin inside a twin-axle braked box trailer. Solid underfoot, warm, lit, sealed against the weather, with proper hot water rather than a hose and a bit of hope.
It's run from Unit 4, 18 Hamburg Way, PE30 2ND, Kings Lynn, Norfolk, covering Norfolk and the surrounding counties. I handle the hires myself: I deliver it, level it, explain how everything works and remain available if you need any help.


WashBox has followed on from HeatSync, our plumbing and heating firm, with the same approach: arrive when promised, complete the work properly and keep customers informed.
It also means this isn't a yard full of hired-in plastic cabins. It's one unit we own, looked after by specialists who already maintain kit for a living.
So if HeatSync is the one ripping your bathroom out, tell us and we'll have the WashBox on your drive the day the old suite comes out, and off it again when your new bathroom is ready to use. If it's a different firm doing the work, it's all the same to us — you still need somewhere to wash and we've got it.

How we work
Four things we won't budge on
We turn up
If we say Friday morning, we're there Friday morning. Set up properly and ready to use before we leave.
You keep your dignity
Being without a bathroom is stressful enough. This is somewhere you'd happily shower before work, not somewhere you'd dread.
We look after it
Braked twin-axle trailer, sealed panels, insulation, ventilation. It's maintained by people who fix bathrooms for a living.
We're local
Norfolk born and based. We know the lanes, the villages and the venues, because we live here too.
