SLATE — the system

Not a
bath bomb.
A system.

SLATE is a modular bath ritual system. You choose the blocks, you build the grid, you set the intention. Every bath is different because every night is.

SLATE — the ritual

Twenty-seven blocks. One soak.

Your day was never one thing. Your bath does not have to be either. A grid is composed, not bought. Every block in it is a decision about tonight.

01

Choose every block

Nothing is fixed. Every position in the grid is yours to set.

02

Mix scent and texture

Pair scent blocks with texture blocks around what tonight actually needs.

03

Stack for intensity

Repeat a block to go deeper. Layer different blocks for something more complex.

04

Different every night

Every bath is different because every night is.

What goes in.
And why.

Every block is a short list of considered ingredients, sourced from specialist bath and cosmetic suppliers. Nothing in here without a reason. Nothing we cannot explain.

What is always true.

The same commitments hold for all thirty blocks.

SLSA is not SLS. It is coconut derived, biodegradable, and chosen for bath use specifically.

Pick a block.

All thirty, twenty scent and ten texture. Everything below updates when you choose.

Scent block

CALM

For when everything feels like too much.

Scent
Lavender · Roman chamomile
Size
2.5cm block, 24g pressed
45%
Sodium bicarbonate
Base · Effervescent

The foundation of the block. Softens the water, carries the fizz, gentle on skin.

22%
Citric acid
Activator · pH balance

Reacts with the base the moment it hits water. That reaction is the fizz. Balances pH gently as it goes.

10%
Epsom salt
Mineral · Recovery

Magnesium sulphate. Supports muscle recovery, eases tension, adds mineral weight to the water.

5%
Arrowroot powder
Skin feel · Press density

A natural starch. Helps the block press cleanly at sharp corners and leaves skin feeling silky.

5%
SLSA
Lather · Surfactant

Sodium Lauryl Sulfoacetate, not SLS. Coconut derived and biodegradable. Soft lather without stripping the skin barrier.

3%
Cream of tartar
Binder · Structure

Food grade acid salt from winemaking. Holds the block's shape and slows the fizz, so the release lasts longer.

3%
Kaolin clay
Softening · Skin barrier

Gentle white clay. Draws out impurities without stripping the skin barrier.

3%
Binding oil
Conditioning · Moisture

Avocado, jojoba, argan or fractionated coconut, matched to what the block is for. Conditions skin and carries the fragrance evenly.

2%
Polysorbate 80
Emulsifier

In every block, so oils disperse through the water instead of floating on it. Without it you get a ring around the bath.
