I Hand Carved a Stone Bathtub, Soaking Pool from a 23,000 lb Rock. DIY

Stone bathtub, hand-carved soaking pool, granite rock — this RingStone project took 3.5 months and 23,000 lbs of solid stone to finish. This is the hardest project of my life, and I made it not for a client, but for a dream: to sell it and buy a home for my parents.

When I found this giant rock, I didn’t know how to even begin. The granite was incredibly dense, filled with quartz veins, and weighed over 10.5 tons (23,150 lbs). Step by step, I cut the base with diamond discs, chiseled the stone with hammer and wedges, and slowly carved out a deep soaking pool with three seats inside.

The polishing alone took almost a month — eight stages of diamond pads from 0 to 1500 grit, followed by natural diamond paste buffing with felt, heated up to 80°C for a permanent shine. Finally, I pressure-washed the granite, sandblasted my RingStone logo inside, and filled the tub with water for the first time.

This is more than a bathtub. It’s a functional art object — a one-of-a-kind piece of natural stone that will last for centuries.

📌 About the project
This hand-carved granite bathtub and stone soaking pool is made from a single natural granite rock. The process included stone cutting with angle grinders (125mm & 230mm diamond discs), chisel and hammer work, wet grinding with compressor air-blow, sandblasting, and high-pressure washing.

The result is a handmade stone bath with timeless design, blending functional art with heritage stonecraft. RingStone specializes in handmade stone products: sinks, bowls, plates, sculptures, and custom stone furniture. But this project was unique — not commissioned, created as a personal challenge and offered for sale.

📍 Dimensions: 2.7 × 2.6 m, ~1 m deep
🪨 Material: solid granite with quartz veins (Mohs 7–8)
💧 Seats: 3 adults comfortably
✨ Finish: 8-step diamond polish + diamond paste buff

The bathtub is available for purchase. Worldwide inquiries are welcome.
