Before you reserve

The questions people ask first. For anything else, write to hello@twelvebath.com.

When can I buy them?

We are refining the formula with our makers now. The list hears first, before anything goes on sale.

Will they stain my tub?

No. Each tile is tinted with kaolin, a fine white clay, never dye, and there is no glitter.

Is it safe for my drain?

Yes. The salts, baking soda, and citric acid dissolve completely, and there is nothing solid to catch in the pipes: no glitter, no petals, no buds. The little clay and oil there is rinses away with the bathwater; run the warm tap for a moment after draining, if you like. On a septic system, bath amounts of these ingredients are generally fine; if yours is sensitive, ask your installer.

Why magnesium?

Magnesium salts have long been drawn into baths. We measure the amount in every tile and print it on the label, and we make no claims about what it does. Magnesium is element 12, hence the name.

Where should I keep them?

Somewhere dry, away from the bathroom. Steam belongs to the evening itself; closed in a cupboard, the others keep their fizz until it's their turn.

What's Deep Soak?

A sachet of 180 g pure magnesium chloride flakes, sold separately. Each tile already carries 65 g of magnesium chloride; add a sachet when you want the bath to hold more (245 g in all). It is unscented and dissolves in a minute or two.
