304 & 316 Stainless Steel

304 and 316 stainless steel

Our stainless-steel shells are designed for outdoor hot-tub use. The Hybrid range is available in 304 stainless steel or a 316 marine-grade upgrade. Check the available options for your chosen model and confirm the selected grade on your order.

304 stainless steel

304 is a stainless-steel option for the Hybrid range as well as specified wood-fired configurations. Appropriate water care and cleaning remain essential.

316 marine-grade stainless steel

316 contains molybdenum, which improves resistance to certain forms of corrosion compared with 304. It is an upgrade worth discussing for coastal exposure. It is not corrosion-proof, and it does not remove the need for correct water treatment or make a saltwater conversion automatically suitable.

Care and warranty

Choose the grade alongside your location, intended use and maintenance plan. Both grades have our 50-year structural shell warranty, subject to the full conditions on our Warranty & Aftercare page. Commercial and short-term rental use require separate written arrangements. Clean the shell and maintain water quality according to the care instructions.
