Reading Garden Room Co. fits bathrooms, WCs and shower rooms into garden buildings across Reading — the upgrade that changes what a garden room *is*. An office with a loo hosts a full workday; a gym with a shower gets used before work; a guest room with a bathroom is genuinely a guest room.

Everything hinges on drainage, and every Reading garden has a different answer — which is why our design visit starts at your manhole cover, not a brochure.

Getting the water there and away

Gravity drainage

Where levels fall toward an accessible foul connection — silent, unpowered, the best answer when the garden allows it.

Pumped systems

Macerators and micro pump stations for gardens that slope the wrong way — modern kit, quiet, dependable, honestly explained maintenance.

One trench, three services

Water, waste and power share a single properly-ducted trench to the house — dug once, invisible forever.

Regs handled

Drainage notifications and bathroom regs are routine paperwork we do — the certificate matters when you sell.

On top of the base building price. Long drain runs and pumped routes price at the top of ranges — the visit settles it exactly.

Fitted like a house, because it is one

Garden-building bathrooms fail when they're fitted like caravans — unheated, under-ventilated, tanked with hope. Ours get full tanking, extraction sized for the room, heating that keeps February showers civilised, and finishes chosen at the visit. Small spaces reward good design: a 1.8m × 1.6m shower room done properly feels boutique-hotel, not budget-ferry.
