1. A Bathroom Isn't Just What You See
Most bathroom problems don’t show up while the fitter is still on site. They appear months later. Mould creeping across ceilings. Tiles loosening. Leaks staining the ceiling below. Electrical issues flagged during a buyer’s survey.
Across Peckham, particularly within SE15, homeowners often discover issues months after completion. Persistent condensation. A faint leak affecting the flat below. Drainage that was never calculated properly.
The reality is simple. Many bathroom fitters do not explain critical technical and compliance details upfront, either because they assume homeowners won’t ask or because explaining them properly would expose shortcuts.
This guide outlines seven matters that should be clearly explained before work begins.
2. Why Peckham Properties Require Careful Planning
Peckham presents a mix of historic terraces and dense modern housing.
You will find:
- Victorian and Edwardian terraces near Peckham Rye Park
- Converted flats above commercial units
- Post-war maisonettes and estates
- Contemporary developments around Peckham Levels
Many properties share soil stacks, have original timber joists and limited service voids. In flats, any drainage or waterproofing failure can directly affect neighbours below.
Bathroom installations in SE15 require structural awareness and regulatory compliance, not just aesthetic design.
3. The 7 Things Bathroom Fitters Often Don’t Explain
1. Building Regulations Compliance Is Not Optional
What it is: Bathroom renovations are governed by UK Building Regulations covering drainage, ventilation, electrics and certain structural works.
Why it matters: Failure to comply can delay property sales, invalidate insurance and result in expensive remedial works.
How it affects Peckham homes: In converted terraces and multi-storey flats across SE15, drainage and ventilation systems may be shared. Historic alterations often lack proper documentation, which surveyors frequently flag.
What a professional fitter should do: Explain which elements are notifiable, liaise with Building Control or operate under a competent person scheme and confirm the certification you will receive upon completion.
2. Ventilation Is More Than “Opening a Window”
What it is: Part F of Building Regulations sets minimum extraction rates. Bathrooms with a bath or shower need 15 litres per second for intermittent fans or 8 litres per second for continuous systems.
Why it matters: Insufficient ventilation leads to condensation, mould growth and deterioration of finishes over time.
How it affects Peckham homes: Many SE15 flats have limited external wall access, making duct routing more complex. Upgraded insulation in older terraces also reduces natural airflow.
What a professional fitter should do: Specify compliant extraction systems, ensure ducting discharges externally and confirm performance levels meet regulatory requirements.
3. Waterproofing and Tanking Are Not the Same as Tiling
What it is: Proper tanking means installing a waterproof membrane behind tiles. Tiles and grout are not waterproof.
Why it matters: Without tanking, water slowly penetrates walls and floors. Damage often appears two to three years later.
How it affects Peckham homes: Converted Victorian terraces and purpose-built flats in SE15 frequently rely on timber floor structures. Even a slow, unnoticed leak can affect the ceiling of the property below and create disputes between neighbours.
What a professional fitter should do: Clearly identify all wet areas, install certified tanking systems before tiling and explain why this stage is essential for protecting both your property and neighbouring flats.
4. Drainage Layouts Must Be Calculated Correctly
What it is: Waste pipes must maintain appropriate gradients and diameter to handle discharge from modern showers and baths.
Why it matters: Incorrect falls lead to slow drainage, odours and recurring blockages that often require invasive corrective work.
How it affects Peckham homes: Lead pipework and 1½ inch waste pipes are still found in Victorian and early 20th century properties.
What a professional fitter should do: Inspect existing drainage thoroughly, maintain correct gradients (typically minimum 1:40) and obtain approval before concealing pipework.
5. Electrical Safety Zones Are Strict for a Reason
What it is: Bathrooms are divided into electrical zones. Each zone has strict IP rating and voltage requirements.
Why it matters: Incorrect lighting or heating installs are dangerous and often fail safety inspections.
How it affects Peckham homes: Older consumer units without modern RCD protection are still present in some properties, particularly in converted terraces.
What a professional fitter should do: Explain zone classifications, install compliant fittings and provide Part P certification on completion.
6. Floor Strength and Structure Are Often Ignored
What it is: Bathrooms are heavy. Tiles, baths, wet rooms and water loads place stress on joists.
Why it matters: Insufficient support can cause movement, cracked tiles or structural sagging.
How it affects Peckham homes: Original joists in Victorian properties were not designed for heavy stone tiles or freestanding baths.
What a professional fitter should do: Assess floor condition and reinforce where necessary before installing finishes.
7. Disruption and Timelines Are Rarely Explained Honestly
What it is: Bathroom renovations disrupt water, electrics and access.
Why it matters: Unrealistic timelines cause stress and conflict.
How it affects Peckham homes: Dense housing and shared entrances in SE15 require careful planning, particularly in multi-storey buildings.
What a professional fitter should do: Provide a realistic programme, coordinate with neighbours or managing agents where required and clearly explain disruption timelines.
