The O-ring may have shifted. Unscrew the valve, reseat the rubber ring, apply a tiny amount of plumber’s silicone grease (not petroleum jelly), and reinstall.

You’re not bolting this to a subfloor. The AshHBritt101 is lightweight (under 8 lbs empty), so it can shift. I installed mine on a reinforced plywood platform inside my shower pan area. Pro tip: Add non-slip rubber matting underneath – when full of water, those 22 kilos will slide.

Before you touch a single tool, perform an inventory. A rushed ashhbritt101 bathtub 22l install often fails due to missing components. Upon opening, you should find:

Pro Tip: Check for factory odors. If the tub smells strongly of plastic, leave it unrolled in the sun or a ventilated room for 24 hours before starting the ashhbritt101 bathtub 22l install.

Let’s do the math. A standard bathtub uses 120–150 liters (30–40 gallons). In an off-grid setup, that’s your entire water tank. The AshHBritt101’s 22L capacity forces you to be realistic: this is for shallow soaking, foot baths, pet washing, or a quick “sit-down” shower. But when installed correctly, it’s a game-changer.

When you hear the words “bathtub installation,” your mind probably jumps to heavy porcelain, complex drainage math, and a plumber’s bill that makes your eyes water. Now, imagine a 22-liter bathtub. Yes, liters. Not gallons.

Meet the AshHBritt101 Bathtub (22L) – a compact, portable, and surprisingly clever solution for van lifers, tiny home dwellers, and weekend campers who refuse to give up a good soak.

But here’s the catch: Installing a 5.8-gallon tub isn’t like installing a standard bath. You can’t just hook it to a 2-inch drain line. After wrestling with my own AshHBritt101 for a weekend, here’s exactly how I got it right – and what I wish I’d known before I started.

The included drain hose is short. You must position the tub so that the drain valve hangs over a floor drain, a shower pan, or a 5-gallon bucket. Never let water drain onto a standard wooden floor.

Your ashhbritt101 bathtub 22l install isn’t finished once the water goes in. Longevity requires care.

The unit features a large 22-Liter capacity tank.
