Spa Area with Indoor Plunge Pool and Skylight
About Spa Area Interiors
Common questions from homeowners.
The centrepiece is a raised indoor plunge pool sitting directly under a curved glass skylight. The arched skylight floods the pool with daylight, so it feels bright and outdoor even though it is inside. Raising the pool above the deck means you sit and step in easily rather than climbing down into it. Clad in warm wood, it reads more like a spa feature than a builder's tank, which is the whole idea.
The walls are clad in grey stacked stone, laid in thin courses for a rough, natural texture. Set into them are sheets of water that run gently down the stone, a moving feature that adds sound and calm. Stone stands up to the damp of a pool room better than paint or wood alone. Arched niches with small sculptures break up the long runs so the walls never feel like one flat surface.
Yes, a vertical garden of living plants covers one wall and softens all the stone and glass. Green against grey stone makes the room feel like a natural retreat rather than a hard pool hall. The floor and pool surround are laid in warm wooden decking, which is comfortable and less slippery underfoot than polished stone when wet. Together the wood and the plants keep a big glass-roofed room feeling grounded and warm.
Blue tufted loungers sit to one side, facing the water for drying off and resting between dips. There is a wall tv on a marble panel too, so the spa doubles as a quiet lounge. Placing the seating away from the splash zone keeps the fabric dry and the pool edge clear. It turns the room into more than a pool, giving you somewhere to sit and stay rather than just swim and leave.
Daylight does most of the work through the arched skylight during the day. At night, brass lantern sconces warm the stone walls, backlit round discs glow like portholes, and hidden strips light the steps and edges. Recessed spots fill in the rest. The mix lets the room shift from a bright daytime pool to a soft, warm evening spa without any harsh overhead glare on the water.
Ventilation is the key, and it is the trade-off of bringing a pool inside. An indoor pool lifts the humidity, so the room needs proper extraction or a dehumidifier to stop damp settling into the finishes. Stone, wood decking and glass are chosen because they cope with moisture better than plaster or fabric would. Keep the air moving and the skylight and vents working, and the surfaces stay sound for the long term.
An indoor pool is the biggest single cost, along with the curved glass skylight above it. The pool structure, waterproofing, the stone cladding, the water walls and the living wall are all specialist trades. The skylight needs proper structural glazing. Furniture and the tv are minor by comparison. This is a room built around a few large fixed features, so the pool and skylight decide most of the budget from the start.
It is more than an ordinary room, and worth knowing up front. The pool needs its water balanced and filtered, the water walls want their pumps and nozzles kept clear, and the living wall needs watering and trimming. Wood decking should be cleaned and re-sealed periodically so damp does not get in. The stone and glass just need washing. It is a rewarding space, but a pool room asks for steady, regular care.
