Our Bathroom Installation Process — Clear, Organised & Professional
At Normz Plumbing, every project follows a structured process — from the first conversation to the final walkthrough. We work across Northamptonshire including Wellingborough, Northampton, Kettering and Rushden, and our approach is the same wherever you are: clear communication, skilled trades and a finished result you'll be proud of.

Consultation & Initial Planning
Every project begins with a conversation. We visit your property, take a proper look at the space and spend time understanding what you're looking for — whether that's a straightforward bathroom replacement or a more involved full home refurbishment.
There's no sales pressure and no obligation. We're here to listen, ask the right questions and give you an honest picture of what's involved.
What we cover during consultation
- Understanding what you want to change and why
- Assessing the existing plumbing, drainage and layout
- Identifying any structural or access considerations
- Discussing your timeline and how you use the space
- Talking through budget range and realistic expectations
- Answering your questions honestly
We work across Wellingborough, Northampton, Kettering, Rushden and surrounding areas — so whether you've found us searching for bathroom fitters in Wellingborough or via a recommendation, we'll come to you.
Building Your Project Plan
Once we understand the project, we put together a clear plan covering scope, materials, timescales and costs — so nothing comes as a surprise.
Design & Project Decisions
Once the consultation is complete, we move into the design and planning stage. This is where the project starts to take shape — layouts are confirmed, fixtures are selected and the final specification is agreed before any materials are ordered or work begins.
Layout & Space Planning
We assess the most effective use of your bathroom space — whether you're keeping the same layout or reconfiguring it entirely to improve flow and functionality.
Fixtures & Fittings
We discuss your preferred style — whether that's a contemporary wet room, a traditional suite or something in between — and confirm your choice of bath, shower, basin and WC.
Tiles & Surface Materials
Wall tiles, floor tiles, grout colours and surface finishes are agreed at this stage. We'll help you think about practicality as well as appearance.
Plumbing & Heating Decisions
We confirm the position of pipework, towel rails, underfloor heating if required, and any changes to the existing plumbing configuration — including feed and waste routes.
Final Specification Sign-Off
Everything is written down and agreed before we proceed. This protects both sides and means there are no misunderstandings when installation begins.
Ensuite & Specialist Projects
If you're planning to convert a bedroom into an ensuite or create a wet room, we'll plan the additional structural and waterproofing requirements at this stage.
Choosing the right fixtures takes time. We never rush this stage — getting the specification right before work starts avoids costly changes later. See some of our completed projects, including a bathroom renovation in Northampton and a small bathroom refurbishment in Wellingborough, to get an idea of what's possible.
Supply, Sourcing & Site Preparation
With the specification agreed, we move into the preparation phase. This is where the project transitions from planning to action — materials are sourced, deliveries are arranged and the site is prepared ready for the installation team to begin.
Good preparation makes a significant difference to how smoothly a bathroom renovation runs. Skipping this stage or rushing it is a common cause of delays — we don't cut corners here.
Material sourcing
We work with trusted suppliers to source the fixtures, fittings and tiling materials agreed during the design stage. Everything is checked on arrival — we won't start work with damaged or incorrect items on site.
Preparation work
Before installation begins, existing fittings are carefully stripped out, the space is protected and any preparatory work — such as wall boarding, sub-floor levelling or initial pipework runs — is completed. This gives the installation team a clean, ready environment to work in.
Minimising disruption
We understand that having your bathroom out of use is inconvenient. We plan the installation sequence carefully to keep the disruption period as short as reasonably possible. Take a look at how we approached a recent bathroom renovation in Rushden or a bathroom fitting in Irthlingborough to see the preparation and removal process in practice.
What Happens at This Stage
A thorough preparation phase protects your property and sets the installation up for success.
- All agreed materials and fixtures sourced and checked
- Delivery scheduled to arrive before installation start
- Existing suite removed and disposed of responsibly
- Floor and walls assessed for condition and prepared
- Wall boarding and sub-floor preparation completed where required
- Initial plumbing routes confirmed and capped
- Adjacent rooms and flooring protected
- Access to water services organised in advance
The Installation Process
This is where everything comes together. Our installation stage covers all the skilled trades required to complete your bathroom — carried out in the right sequence, to a professional standard.
-
First Fix Plumbing
All pipework for hot and cold water supplies, waste routes and drainage connections are installed and pressure tested before the walls and floors are closed up. Our plumbing and heating services are carried out by experienced tradespeople familiar with domestic installations across Northamptonshire.
-
Wall & Floor Preparation
With first fix plumbing complete, walls are boarded or plastered where necessary, and floors are checked for level. This stage ensures structural surfaces are completely sound, square and ready for subsequent trades across our standard shower room installations and full wet rooms.
-
Tiling
Wall and floor tiling is carried out once surfaces are properly prepared and cured. We work to the pattern and layout agreed during the design stage, paying close attention to cuts, alignment and grout line consistency — the details that make the difference to the finished result.
-
Second Fix Plumbing & Fitting
With tiling complete, sanitary ware, shower enclosures, brassware, towel rails and accessories are fixed in position and connected. This includes bath panels, mirror units and any storage furniture agreed in the specification. We've completed shower installations across Northampton and throughout the county.
-
Final Checks & Quality Review
Before we call the project complete, every connection is checked, every surface is inspected and any snagging items are addressed. We don't hand a project over until we're confident it meets the standard we'd expect in our own homes.
Completion & Project Handover
The completion stage is more than just packing up tools. Before we leave your property, we carry out a thorough final review and walk you through the finished bathroom together.
We want you to be fully satisfied with the result and comfortable using everything that's been installed — from operating your new shower to understanding how the valves and controls work.
What the handover covers
We clear the site, remove all waste and leave your bathroom clean and ready to use. You'll be shown how everything works and given the opportunity to raise any queries before we consider the project closed. View some of our completed projects to see the standard we aim for — including a bathroom remodel in Northampton and a bathroom installation in Finedon.
Final snagging review
Every element is inspected against the agreed specification. Any minor items are addressed before we proceed to handover.
Customer walkthrough
We walk through the completed bathroom with you — explaining how everything operates and answering any questions you have.
Site cleared and cleaned
All waste, packaging and tools are removed. We leave the space tidy and ready for you to use immediately.
Project officially handed over
Once you're happy, the project is complete. Any follow-up queries are always welcome — we're a local business and we're easy to reach.

We employ skilled tradespeople across plumbing, tiling and fitting — not a single generalist doing everything. The right people for each stage of the job. See examples in our bathroom fitting portfolio across Northampton.
Local Knowledge

Minimal Disruption
We plan the installation sequence to keep downtime as short as possible. Your property is treated with respect throughout — floors and adjacent rooms are protected from start to finish.
Full Service Capability
Beyond bathrooms, we also cover plumbing and heating and full home refurbishment — so if your project expands in scope, we can handle it without bringing in additional contractors.
