The brief for a tropical bathroom
Write the brief before the mood board. A bathroom in Grenada, Carriacou or Petite Martinique is used by people arriving straight from the sea or the pool, it is often ventilated by a louver rather than a fan, and it sits in a house where the air is humid for most of the year. So the floor must grip when wet, the water must leave quickly, and everything must dry between uses. Every decision below follows from those three lines. Write them down and hand them to the tiler, because a bathroom is the room where good intentions most often get lost between the drawing and the tiling.
Falls, drains and where the water goes
Water management is the whole job, and it is set out before a single tile is ordered:
- Give the shower area a consistent fall to the drain across its full width, not just near it.
- Keep the fall on the rest of the floor gentle but real, so mopping water finds the drain too.
- Place the drain where the fall can be built without cutting awkward wedges of stone.
- Waterproof the substrate properly under the whole wet area, not only inside the shower.
- Check the fall with a level and a bucket of water before the tiler leaves the site.
The falls are drawn before the stone is ordered, not discovered afterward. Get this right and the tile choice becomes straightforward; get it wrong and no finish will save the room.
Floor tile choice for a wet floor
Two things decide the floor: texture and size. A brushed or sandblasted surface keeps grip once a film of water is on it, while a smooth honed finish belongs in the dry half of the room at most. Smaller formats let a tiler build the fall in small steps instead of forcing a large piece to twist, and they put more joint lines under a wet foot. That combination, rather than any single product, is what makes a shower floor feel secure. Keep the tone the same as the rest of the house so the bathroom does not read as an afterthought, and remember a smaller piece is easier to replace years later.
Walls, niches and vanity tops
The vertical surfaces take no traffic, so the rules relax and the details matter more:
- Larger wall pieces reduce joints and make a small room read calmer.
- Honed walls are fine and easier to keep clear of soap film than textured ones.
- Line niches with full pieces and slope the base slightly so water drains out.
- Use the same stone for a vanity top so tone matches across the room.
- Keep a discreet joint where the wall meets the floor so the two can move.
Order wall and floor stone together so the tone matches across every surface in the room.
Thresholds that actually work
The door line is where wet rooms succeed or fail, and it deserves as much attention as the tile specification for shower floors itself:
- Use one full-width piece rather than two cuts meeting in the middle of the opening.
- Set a modest upstand or a level change so shower water cannot cross the line.
- Keep the finish continuous underfoot so nothing catches a bare toe.
- Seal the perimeter joint with a flexible material, not with rigid grout.
None of this is expensive; it is simply detail that has to be decided before the tiler cuts anything.
Ventilation and what it saves you
A bathroom that dries between uses stays clean with very little effort. One that stays damp grows biological film in the joints within a season, especially through the June-to-December rains when the air outside is already saturated. Louvers on two sides, a vent above the door or an extract fan on a timer will each do more for the long-term look of the stone than any sealer. This is the cheapest specification decision in the room and the one most often skipped. Where a bathroom has no external wall, plan the extract before the tiling, since running a duct afterward means opening finished surfaces that were expensive to lay.
Resort bathrooms and family bathrooms
The resort corridor around La Sagesse and Grand Anse builds to a different maintenance model than a private villa. Hotels have daily housekeeping, so they can carry larger formats and calmer finishes. A family house at True Blue or Westerhall is cleaned weekly and used by children with sandy feet, which argues for more texture, smaller floor pieces and a tone that hides a day of use. Specify honestly for who actually lives there. That expectation gap is worth naming early, since owners often ask for hotel details on a domestic cleaning budget, and the specification can be adjusted before anything is ordered.
Lead times and getting it to site
Bathrooms are usually the last rooms finished and the first to be delayed, so order early. A shortage of a few pieces stops the whole room, so buy the bathroom in one go:
- Agree finishes and formats before shipping, since both are applied before packing.
- Allow the sea leg from Florida into the Port of St George’s when setting dates.
- Confirm CARICOM duty, VAT at fifteen percent and the Customs Service Charge with your broker.
- Add the separate cargo-boat sailing into Tyrrel Bay for anything bound for Carriacou.
