Why Renovation Is the Best Time

During a bathroom renovation, you have options that are difficult or expensive later:

  • Access to pipes: Walls are open, plumbing is accessible
  • Electrical work: First fix means easy cable routing
  • Design integration: Choose size and position before tiling
  • Cost efficiency: Adding heating during reno is cheaper than retrofitting

Step 1: Decide Your Heating Type

Option A: Electric Only

Best If:

  • No central heating pipes in bathroom
  • You want the simplest installation
  • Independent year-round operation is important
  • Budget for installation is limited

Installation needs: Electrical socket or fused spur

Option B: Dual Fuel (Central Heating + Electric)

Best If:

  • You have central heating pipes nearby
  • You want lowest running costs
  • Maximum flexibility is important
  • This is your main family bathroom

Installation needs: Plumber + electrician

Option C: Central Heating Only

Best If:

  • Budget is very tight
  • You don't need summer heating
  • Bathroom has other heat sources
  • Replacing existing central heating rail

Installation needs: Plumber only

Step 2: Calculate the Right Size

Use the BTU Calculator

Our BTU Calculator tells you exactly what heat output you need based on:

  • Room dimensions (length × width × height)
  • Window size and type
  • Insulation quality
  • Room location (ground floor, exposed walls)

Quick Reference Guide

Bathroom Size BTU Needed Typical Wattage
Cloakroom (under 3m²) 400-600 100-200W
En-suite (3-5m²) 600-1000 200-300W
Standard bathroom (5-8m²) 1000-1600 300-500W
Large bathroom (8m²+) 1600+ 500W+ or multiple

Step 3: Plan the Position

Best Positions for Towel Rails

  1. Opposite the shower/bath - Easy access when stepping out
  2. Near the door - Grab towel on way in
  3. Next to vanity - Convenient for hand towels

Positions to Avoid

  • Directly above bath (Zone 1, safety concerns)
  • Behind door that opens against it
  • Blocking access to controls or switches

Plan for Electrical/Plumbing

Tell your builder/plumber where you want the towel rail before first fix:

  • Electric: Cable route to fused spur position
  • Central heating: Pipe runs to both valve positions
  • Dual fuel: Both of the above

Step 4: Choose Style & Finish

Styles

Style Best For Look
Ladder/Traditional Most bathrooms Classic, timeless
Curved Extra towel space Elegant, generous
Flat Panel Modern interiors Sleek, minimal
Designer Statement piece Unique, eye-catching

Finishes

  • Chrome: Classic, matches most fixtures, easy to clean
  • White: Blends with walls, modern, suits minimalist bathrooms
  • Anthracite/Black: Bold statement, suits contemporary designs
  • Brushed finishes: Hides fingerprints, sophisticated look

Match Your Fixtures

Consider matching or coordinating with:

  • Taps and shower fittings
  • Door handles and accessories
  • Mirror frames
  • Light fittings

Step 5: Budget Planning

Typical Costs

Item Electric Dual Fuel Central Heating
Towel rail £100-300 £120-350 £80-250
Element/valves Included £50-80 £30-50
Installation* £50-100 £150-250 £100-150
Total £150-400 £320-680 £210-450

*Installation costs lower during renovation as trades are already on site

Step 6: Timing Your Order

When to Order

  1. 4-6 weeks before first fix: Order towel rail
  2. At first fix: Install pipework/electrical
  3. After tiling: Mount towel rail
  4. Final fix: Connect and test

What to Tell Your Trades

  • Exact position: Height from floor, distance from corners
  • Type: Electric, dual fuel, or central heating
  • Connection point: Where element/valves will be
  • Weight: Heavy rails may need extra wall support

Common Renovation Mistakes to Avoid

Don't Make These Errors:

  1. Ordering after tiling - Limited to certain sizes
  2. No electrical provision - Stuck with central heating only
  3. Wrong zone placement - May need expensive relocation
  4. Undersizing - Room won't heat properly
  5. Forgetting summer heating - Central heating only means cold towels in summer
