How to choose a towel rail
A towel rail in the bathroom does two things: dries towels and adds local comfort heat. If you choose only by the “nicest chrome”, you risk a hydronic model with no heating connection — or electric where there is no safe socket. This guide organises towel rail choice.
Comparison: electric or hydronic. Heating map: heating and hot water.
Step 1 — hydronic or electric
| Hydronic (from heating) | Electric | |
|---|---|---|
| When | There is a heating circuit / renovation with a connection | No convenient heating line; need it in summer too |
| Plus | Heat “from the system” | Independent of heating season |
| Minus | Seasonal; needs the right connection | Uses electricity; needs safe electrics in a wet zone |
Inventars Semko examples below are typical stainless hydronic rails — check connection and kit on the card.
Step 2 — shape U or M
U — simpler ladder/loop shape, often more compact. M — more crossbars, more towel space. Choose by habit: how many towels you dry at once and how wide the wall is.
U examples: Semko U 250×400, U 250×500, U 250×800, U without screws. M examples: Semko M 500×400, M 500×450.
Step 3 — size against the wall
On the card: width × height (or the reverse — read carefully). Leave space for feeds and, if needed, valves. Lower/narrower niche → more compact U; wider wall and more towels → M or longer U.
Material and moisture
Bathroom = moisture. Stainless steel is a typical choice. Check surface finish and manufacturer notes on cleaners (chlorine cleaners damage many finishes).
Typical mistakes
- Ordering a hydronic model when there are no heating outlets in the wall.
- Taking too narrow a rail “because it fitted in the photo”, but two towels do not hang.
- Forgetting electrical safety in a wet zone (electric type).
- Mixing a towel rail with a room radiator — it is not the main heat source for a large room; radiator: guide.
Short path
- Hydronic or electric — comparison.
- Measure the free wall; choose U or M.
- Compare 2–3 cards (U 400, U 500, M 400).
- Check connection / kit before ordering.

FAQ
Does a towel rail replace a radiator?
Usually no. It is a comfort and drying device. For room heat see radiators.
Is U 800 “better” than U 400?
Longer — more towel space, but needs wall. Take by space and habit, not the biggest mm.
