Brilliant choice \u2013 feels so much more spacious, doesn&apos;t it? No clunky shower tray to trip over. But let me tell you, I learned the hard way. My mate\u2019s place in Hackney? Looked like a dream until the downstairs neighbour knocked on the door last spring, complaining about a damp patch on their ceiling that was spreading like a bad rumour. Nightmare.<\/p>\n<p>See, the trick isn\u2019t just the shower tray itself. Honestly, that\u2019s maybe\u2026 2% of the battle? It\u2019s all about what\u2019s underneath and around it. Like building a tiny, waterproof fortress for your feet.<\/p>\n<p>First off, the floor needs to slope. And I don\u2019t mean a gentle tilt you can barely notice. I mean a proper fall, directed straight towards that drain. I once saw an install in a Chelsea refurb where the tiler, lovely bloke, got the angle wrong. Water just pooled in the corner. You\u2019d step out and your towel would get soaked from the splashback! Had to rip the whole lot up. The money\u2026 ouch.<\/p>\n<p>Which brings me to the tanking. That\u2019s the magic word. Tanking kits \u2013 liquid membranes, fabric tapes, the whole lot. You paint or trowel this rubbery stuff onto every single surface: floor, walls, corners, the lot. It\u2019s like giving your entire shower area a seamless, flexible raincoat. Don\u2019t skimp here. I remember doing my own en-suite and my back was killing me from crouching, sealing every little joint and screw hole. Smelled a bit chemical-y for a day, but the peace of mind? Priceless.<\/p>\n<p>The drain is the star of the show, really. Get a linear one if you can. Sleek, modern, and it catches water so much better than a tiny round grate. Make sure it\u2019s properly sealed to the membrane below. That connection point is where leaks love to start. I\u2019m a fan of the ones with a removable grate for cleaning \u2013 you wouldn\u2019t believe the hair that collects. Grim.<\/p>\n<p>Tiles need a specific adhesive and grout, too. Flexible, waterproof stuff. Normal grout will suck up moisture like a sponge and before you know it, you\u2019ve got mould and a musty smell. Trust me, I\u2019ve smelled it. Like a forgotten gym kit.<\/p>\n<p>Oh, and test it! Before you even think about tiling, plug the drain, fill the whole area with a few inches of water, mark the level, and leave it for a day. If the water drops, you\u2019ve got a leak. Find it and fix it *now*. It\u2019s a boring, tense 24 hours, but it beats finding out six months later.<\/p>\n<p>So yeah, the wet room shower tray? It\u2019s just the final piece. The real heroes are the slope, the tanking, and that drain. Get those right, and you\u2019ve got a sanctuary. Get them wrong, and you\u2019ve got a very expensive, soggy problem. My two pence, anyway.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Alright, so you&apos;re thinking about a wet room, yeah?
