Oat, Milk & Honey
Warm. Creamy. Comforting.
Warm oats, creamy milk and golden honey with a soft, comforting sweetness. Cozy, smooth and gently gourmand.

Sensual. Rich. Moroccan.
Velvety Moroccan roses, soft floral petals and a warm, silky argan oil finish. Romantic, rich and softly sensual.
Juicy Peach
Fresh. Bright. Summery.
Fresh-cut peaches, soft peach skin, a hint of nectar and warm summer sweetness. Juicy, bright and deliciously fruity.
Salted Caramel
Gourmand. Rich. Buttery.
Golden caramel, warm butter and a touch of sea salt with a soft, creamy sweetness. Cozy, rich and deliciously indulgent.
Jasmine Flowers & Mediterranean Orange
Bright. Sunny. Mediterranean.
Soft jasmine blossoms, juicy Mediterranean orange and a touch of warm citrus zest. Fresh, floral and sun-soaked.
Strawberry Shortcake

Juicy strawberries, soft vanilla cake and whipped cream with a warm, sugary finish. Sweet, creamy and deliciously nostalgic.

2,400+ Bathers Can't Be Wrong
"I bought the Honey, Milk & Oatmeal and I genuinely teared up a little. It smells like the best memory you can't quite place. The bubbles were INSANE — my whole tub was like a bubble cloud."
Sophie M.
New York, NY
"Finally a bubble bath that doesn't run out in 3 uses. I pour SO generously now and it still lasts forever. The Lavish Lilac scent is just... everything. My bathroom smells like a luxury spa."
Jade R.
Los Angeles, CA
"The Ecstasy of Roses is the most romantic scent I've ever put in a bath. I light candles, pour half the bottle (guilt-free!), and disappear for an hour. Pure magic."
Margaux T.
Toronto, ON
"Banana Caramel Cupcake smells EXACTLY like it sounds. My 7-year-old self is losing her mind right now. But like, in an elegant, luxurious way. Totally obsessed."
Elena P.
Miami, FL
"The Freshly Cut Peach was my first Castel and now I have all 5 scents. The bottle is MASSIVE and the bubbles last the entire bath. Worth every penny — actually worth so much more."
Ava K.
Seattle, WA
"I gave this as a gift to my mom and she called me to say it was the best gift she'd ever received. We both now have every scent. Castel has become a family ritual."
