Garden Rooms with Bathrooms in Reading
Insulated garden rooms, offices and studios built across Berkshire. Free surveys, fixed written quotes, tidy workmanship.
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.
What bathrooms add to the build
| Addition | Adds to base building | Notes |
|---|---|---|
| WC + basin | £4,800 – £7,500 | The workday enabler |
| Full shower room | £7,000 – £10,500 | Incl. drainage works |
| Shower room + kitchenette | £11,000 – £16,000 | Annexe territory |
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.
Garden annexes
The full self-contained version.
Garden gyms
The most popular bathroom pairing.
