The Iris — Stainless Steel Designer Towel Rails

Choosing the right towel rail affects warmth, durability and the look of your bathroom. The Iris range from Budget Radiators pairs a refined stainless finish with clear technical specifications so you can match style to performance without guesswork. This page explains practical differences across Iris models, how to size them correctly, and what to confirm before you buy.

Key characteristics of the Iris range

Finish build: polished stainless steel ladder and vertical designs that resist flaking and cosmetic corrosion compared with plated alternatives.
Material options: standard 304 stainless for most homes; 316 specification where extra chloride resistance is needed (coastal or poolside settings).
Connection types: hydronic (central-heating), electric elements, and dual-fuel variants to allow year-round towel warming.
Clear outputs: model pages list Watts and BTU figures at industry-standard ΔT values so you can size precisely.

Sizing and heat output — practical steps

Follow three short steps to match an Iris model to your room:

Measure room volume (length × width × height in metres).
Use a BTU/Watt calculator to estimate the required output for the bathroom (remember window size and insulation). Then treat the towel rail’s Watts as the amount of heat it will supply — add to any existing radiators if it is not your only heat source.
Compare the product’s stated Watt/BTU figure (check the specification table on the Iris product page) and choose a model that meets or slightly exceeds the calculated requirement.

Tip: convert between Watts and BTU where necessary: 1 W ≈ 3.412 BTU/h so you can compare numbers from different suppliers easily.

Material choice — when to pick 304 or 316

304 stainless is appropriate for most UK bathrooms and provides a strong, low-maintenance finish. Choose 316 stainless where the rail will face salt-laden air (coastal locations) or chemical exposure (spa or pool environments). If you need guidance for a specific property, check the product specification or ask a supplier representative for the weld and passivation details.

Connection types and installation considerations

Iris models are available for different heating systems:

Hydronic (central heating): connect directly to the hot water loop—suitable when the boiler provides regular heat.
Electric: fitted with an electric element so towels stay warm out of season; requires a qualified electrician for safe installation and compliance with UK wiring regulations.
Dual-fuel: offers the convenience of both systems and is a practical pick for year-round use.

Also confirm pipe-centre measurements and valve compatibility (angled or straight valves, thermostatic options) before checkout.

Warranty, documentation and support

Check the Iris technical sheet for the manufacturer warranty and pressure-testing information. Product pages typically include downloadable spec PDFs and fitting guides — keep these for the installer and for future maintenance reference. If you require faster delivery or trade quantities, compare stock and dispatch options across retailers.
