An outdoor shower is one of the highest-return upgrades for a Greek holiday rental, seafront home, or hotel — guests rinse off sand and salt before entering, and the property stays cleaner. The video above walks through the full installation from enclosure to plumbing, while this article breaks the process into five clear steps you can follow on any property. Whether you are connecting to an existing water line or running a dedicated supply, the principles are the same throughout Greece and the islands.
Why Outdoor Showers Make Sense for Greek Properties
Greece's long swimming season — easily eight months on the islands — means guests and family members track in salt water, sand, and sunscreen every single day. A permanent outdoor shower at a pool edge, garden wall, or terrace entrance eliminates most of that wear on interior tiles and plumbing fixtures.
Holiday rental operators in particular see the shower as a selling point in listing photos and a maintenance reducer in practice. Hotels and villas that already have one consistently cite it as an amenity guests mention in reviews.
Planning Before You Pick Up a Tool
The two decisions that shape everything else are location and water supply. Choose a spot with natural drainage away from foundations — a gravel bed, a sloped paved area, or a connection to an existing drain. Then decide whether you will tap an existing cold-water line (simplest), run a dedicated hot-and-cold supply from the house, or use a solar-heated tank on the roof (very common in Greece and a natural fit for a standalone outdoor unit).
Check with your local municipality (Demos) whether a fixed outdoor shower requires a small building permit. In most Greek jurisdictions a wall-mounted unit without an enclosed structure does not, but an enclosure with a foundation slab may. Confirm before you pour concrete.
How to Install an Outdoor Shower: 5 Steps
- 1
Plan the water supply and drainage
Locate the nearest cold-water supply line and decide whether to add a thermostatic mixer for hot water. Mark the drain exit point — ideally sloping at least 1–2 cm per metre toward a gravel soakaway or a connection to the main drain. Sketch the pipe run before buying materials so you know exactly which fittings and lengths you need.
- 2
Run and connect the supply pipes
Shut off the main water supply and tap into the closest cold-water line using a T-fitting and a shutoff valve dedicated to the shower. If adding hot water, run a second line from the boiler or solar tank. In Greece, 16 mm multilayer (PEX-AL-PEX) pipe is the most common choice for outdoor runs — it handles UV exposure and thermal expansion better than plain copper in direct sun. Bury any underground sections at least 40 cm deep to protect them from accidental damage.
- 3
Mount the post or wall fittings
For a freestanding shower, set a stainless-steel or powder-coated aluminium post in a concrete footing — mix a bag of fast-set concrete, drop the post in plumb, and allow 24 hours to cure. For a wall-mounted unit, drill into the masonry with a hammer drill, insert stainless-steel anchor bolts, and attach the valve body bracket. Either way, use only marine-grade or 316-stainless fixings; standard zinc hardware corrodes quickly in coastal Greek air.

Install the valve, showerhead, and enclosure
Thread the supply pipes through the post or wall, connect them to the thermostatic or single-lever valve with compression or push-fit fittings, and attach the showerhead. Hand-tighten first, then snug with a wrench — do not overtorque chrome fittings. If you are adding a privacy enclosure (cedar, composite, or powder-coated aluminium panels are all popular), fix the frame to the post or to separate ground anchors and attach the panels, leaving a gap at the base for drainage.
- 5
Test, seal, and finish the area
Turn the water back on slowly and check every joint for drips. Flush the showerhead for two minutes to clear any pipe debris. Seal any penetrations through masonry with silicone rated for outdoor use. Lay the finished floor surface — teak decking, natural stone, or anti-slip ceramic tiles — over the prepared drainage layer. Finally, label the dedicated shutoff valve clearly so you or a caretaker can isolate the shower for winter or when the property is unoccupied.

FAQ
- Do I need planning permission to install an outdoor shower in Greece?
- For a simple wall-mounted shower head with no enclosure or slab, most Greek municipalities do not require a permit. If you plan a permanent enclosed structure with a concrete foundation, a small 'small-scale work' notification (ypeuθyni dilosi) may be required. Check with your local Demos or a licensed engineer before starting.
- Can I have hot water in an outdoor shower without running a long pipe from the house?
- Yes — a roof-mounted solar hot-water tank (ilioθermiko) is the standard Greek solution and works very well for an outdoor shower. The tank heats passively throughout the day, and a short insulated pipe run to the shower keeps heat losses low. You can also install a small point-of-use electric boiler near the shower enclosure as a backup for cloudy days.
- What materials hold up best to the Greek coastal environment?
- Opt for 316-grade stainless steel for all fixings, valves, and showerheads — it is significantly more corrosion-resistant than standard 304 stainless in salt air. For enclosure panels and decking, teak, iroko, or high-quality composite wood all perform well. Avoid galvanised steel or standard aluminium near the sea, as both corrode quickly without a marine-grade coating.
