Overview

## What Does a Bathroom Installation Include?

A bathroom installation is the complete process of removing an existing bathroom and replacing it with an entirely new suite, fixtures, tiling, and finishing. Unlike a simple renovation or refresh, a full installation involves first-fix plumbing, waste rerouting, waterproofing, and structural preparation — all before the visible elements are even fitted.

At DPS, our installations cover every stage: careful strip-out of the old bathroom and responsible waste disposal, inspection and preparation of the subfloor and walls, first-fix plumbing (repositioning supply pipes and waste runs to suit the new layout), waterproof tanking of all wet areas, wall and floor tiling, second-fix plumbing (connecting sanitaryware, taps, and showers), electrical work (extractor fans, heated towel rails, underfloor heating), silicone finishing, and a final quality check.

We install bathrooms in all property types across Manchester — from compact terraced house bathrooms where every millimetre matters, to spacious detached homes where design freedom allows for freestanding baths and walk-in wet rooms. We also fit en-suites in loft conversions, downstairs WCs, and accessible bathrooms for elderly or disabled residents.

Every installation starts with a free home survey. We measure the space, discuss your preferences, identify any structural or access challenges, and then provide a fixed-price quote that covers everything — materials, labour, waste removal, and finishing. There are no extras, no day rates, and no surprises.

## Real Examples of Our Work

Why It Matters

## The Real Cost of a Bad Bathroom Installation

A bathroom installation that cuts corners on preparation creates problems that surface months — sometimes years — later. The most common failure point is inadequate waterproofing behind shower areas. Without proper tanking membrane, moisture penetrates through grout joints, saturates plasterboard, and causes it to crumble. Tiles fall off. Mould colonises the wall cavity. The entire shower wall needs stripping and rebuilding.

Poor floor preparation is the second most common cause of installation failure. If tiles are laid on a flexing timber floor without proper ply boarding and decoupling membrane, they crack along the grout lines within the first winter as the house structure moves with temperature changes. Replacing cracked floor tiles means removing the toilet, the vanity unit, and anything else sitting on the floor — effectively redoing half the bathroom.

Incorrectly installed waste pipes are invisible once tiled over, but they cause persistent problems: slow-draining sinks, gurgling toilets, and sewer odours in the bathroom. These issues stem from insufficient fall (gradient) on the waste pipe, missing or poorly positioned air admittance valves, or joints that weren't solvent-welded properly. Fixing concealed waste pipes means cutting into walls or floors to access them.

The single biggest risk of a cheap installation is water damage to the rooms below. A shower tray that isn't bedded properly on a full mortar base can flex under use, breaking the silicone seal at the edges. Water runs underneath, through the floor, and into the ceiling below. The damage often isn't visible until the ceiling starts to bow or stain — by which point thousands of pounds of remedial work is needed.

How We Work

## Our Proven Process

1

### Free Home Survey

We visit your home, measure the space precisely, discuss layout options and product choices, and identify any structural or plumbing considerations specific to your property.

2

### Detailed Fixed-Price Quote

You receive an itemised quote within 48 hours, covering everything from strip-out to final clean. Materials, labour, waste disposal — all included. The price you see is the price you pay.

3

### Material Selection Support

We help you choose sanitaryware, tiles, brassware, and accessories that suit your budget and style. We can supply everything through our trade accounts or work with items you've sourced yourself.

4

### Strip-Out & Preparation

The old bathroom is carefully removed and all waste disposed of. We then prepare the substrate — levelling floors, replastering walls, rerouting pipes, and installing any structural reinforcement needed.

5

### Installation

Plumbing first-fix, waterproofing, tiling, second-fix plumbing, electrics, and finishing are completed in sequence by our team. We keep you updated daily and maintain a clean, safe working environment.

6

### Handover & Guarantee

We walk through the completed bathroom with you, test every fixture and fitting, and hand over your written guarantee and any relevant compliance certificates.

Benefits

## What You Get When You Choose DPS

### Everything Under One Roof

Plumbing, tiling, electrics, carpentry — all handled by our team. No coordinating between trades, no finger-pointing when something doesn't align.

### Fixed Price, Zero Extras

Our quotes include every element of the installation. Waste removal, making good, silicone finishing — it's all in the price. We've never surprised a customer with an unexpected invoice.

### Minimal Disruption

We plan our installations to minimise the time your bathroom is out of action. Most standard installations are completed within 5–7 working days.

### Quality Materials by Default

We use polymer-modified tile adhesives, waterproof tanking systems, brass fittings (not plastic), and branded sanitaryware as standard. Cutting corners on materials is not something we do.

### Clean & Tidy Daily

At the end of each working day, dust sheets are folded, waste is bagged, and your home is left in a liveable state. We know you're living around the work.

### Aftercare Included

Our guarantee covers workmanship. If a tap starts dripping, a tile comes loose, or a drain slows down within the guarantee period, we return and fix it at no charge.

In Detail

## Bathroom Installation: Technical Detail & Specifications

Every bathroom installation we carry out follows a consistent methodology refined over 13 years and 500+ completed projects. This section explains the technical standards we apply so you understand exactly what goes into a DPS bathroom.

Subfloor preparation begins with assessment of the existing surface. For concrete subfloors, we check for damp (using a moisture meter, not guesswork) and apply DPM if readings exceed 75% RH. Self-levelling compound is applied where the floor is more than 3mm out of level over a 2-metre span. For timber subfloors, we install 12mm marine plywood, screwed at 300mm centres, to create a rigid, stable base for tiling.

Waterproofing is applied to all wet areas without exception. We use a system approach — primer coat, liquid membrane, tape reinforcement at internal corners and pipe penetrations, and a second membrane coat. The entire wet zone is sealed before any tiling begins. This isn't optional; it's fundamental to a bathroom that lasts 15–20 years.

Tiling methodology varies with tile format. Standard wall tiles (up to 300x600mm) are fixed with standard flexible adhesive. Large-format tiles (600x600mm and above) require back-buttering — applying adhesive to both the wall and the tile back — to achieve full bed coverage and prevent hollow spots. Natural stone requires special adhesives and pre-sealing.

Waste pipe installations follow Building Regulations Part H. Minimum falls of 1:40 for 40mm pipes and 1:80 for 100mm soil pipes. Air admittance valves are installed where direct venting to the soil stack isn't practical. All waste joints are solvent-welded (not push-fit) for permanent, leak-free connections in concealed locations.

Shower tray installation uses a full mortar bed for rigid support, regardless of whether the tray is stone resin, acrylic, or ceramic. Frame-mounted trays are levelled with adjustable legs and the void underneath is accessible for future maintenance. We never foam-fill under shower trays — it makes future access impossible.

Silicone application — often the last thing done but one of the most important — uses Dow Corning 785 or equivalent sanitary-grade silicone in a colour-matched finish. Joints are tooled with a curved profile for water shedding and aesthetic consistency. We mask before applying for clean, parallel lines.

Electrical work in bathrooms must comply with BS 7671 (IET Wiring Regulations) and Building Regulations Part P. All circuits in the bathroom zone are RCD protected. Extractor fans are wired with overrun timers. Heated towel rails are connected via fused spurs. We arrange Part P notification where required.
