Shower Spares

Keep your customers’ showers running at peak performance with City Plumbing’s extensive selection of genuine shower spares and replacement parts. Having a reliable source for high-quality components is essential for finishing jobs efficiently and avoiding costly callbacks. Our range is vital for maintaining the core functionality and safety of any bathroom, ensuring that thermostatic controls remain precise and fixtures stay leak-free for years to come. Explore our comprehensive inventory, featuring spotlight brands like Bristan and Croydex, as well as exclusive Aqualisa components built to last. 
Shower Spare Ranges Available At City Plumbing
Our extensive selection of shower spares is designed to cover every eventuality, from minor aesthetic refreshes to critical internal repairs. Here’s a breakdown of our core product range:

Shower Screen Seals

Maintain a watertight bathroom with our range of durable screen seals. Designed to fit a range of glass thicknesses, these high-quality PVC strips prevent leaks and water damage to flooring. We stock a variety of profiles, including bottom "flipper" seals and side magnets, making it easy to replace discoloured or perished strips and restore a hygienic, crystal-clear finish.

Wall Brackets & Outlets

The backbone of any shower setup, our wall brackets and outlets combine robust construction with sleek design. Whether you are installing a fixed overhead rose or a flexible slider rail, our brackets provide secure, stable mounting. Our wall outlets (elbows) are available in various finishes, ensuring a seamless, leak-proof connection between your concealed pipework and the shower hose.

Flow Regulators & Cartridges

The "engine room" of the shower, these components are essential for restoring performance. We provide thermostatic cartridges to fix temperature fluctuations and flow cartridges to solve dripping issues. Additionally, our flow regulators are a must-have for eco-conscious projects, allowing you to maintain a powerful shower experience while significantly reducing water consumption.

Accessories

Complete the job with those essential finishing touches. Our accessory range includes everything from replacement shower hoses and multi-mode handsets to riser rail soap dishes and hose retainers. These high-quality parts enable quick upgrades to existing systems, improving both the appearance and daily usability of the shower.
The Benefits of A Comprehensive Spares Range
In the world of plumbing, sometimes the smallest part makes the biggest difference. Whether you're a homeowner looking for a quick fix or a professional maintaining a large property portfolio, the Shower Spares & General Spares category is your first line of defence against household disruption.
Here’s why having access to a comprehensive spares range is essential:

Curbing Leaky Bathroom Appliances

A dripping tap or a leaking shower head is more than just an annoying sound, it’s a waste of thousands of litres of water per year. Often, the entire unit is perfectly fine, and you simply need a replacement cartridge, washer, or O-ring. Accessing the right spare part allows you to stop leaks at the source, preventing water damage to flooring and joists without the cost of a full replacement.

Replacing Worn-out Seals

Over time, constant exposure to water, heat, and cleaning chemicals causes rubber seals and gaskets to perish. When shower screen seals or internal valve gaskets become brittle or mouldy, they lose their watertight integrity. Replacing these perished seals is the most cost-effective way to refresh your bathroom’s hygiene and ensure water stays exactly where it’s supposed to be.

Improving Water Efficiency

Modern spares allow you to "spec-up" your current fixtures. By swapping out old components for modern flow regulators or aerators, you can significantly reduce your water consumption. This is a simple, high-impact way to lower utility bills and make an older bathroom more environmentally friendly without a complete overhaul.

Modernisation of Older Bathrooms

You don’t always need to rip out the tiles to get a modern look. Replacing dated or tarnished handles, wall plates, and riser rails with contemporary alternatives can instantly revitalise an older bathroom. It’s the "facelift" approach to renovation—keeping the high-quality internal brassware while updating the visible touchpoints.

Upgrades to Existing Systems

Sometimes a spare part is an opportunity for an upgrade. Switching a standard shower handset for a multi-function version or replacing a basic manual valve with a thermostatic cartridge enhances the user experience. Spares allow you to customise your existing setup to better suit your lifestyle, providing better pressure, improved safety, and a more luxurious feel.
Frequently Asked Questions About Shower Spares
Here are the answers to our frequently asked questions for our Shower Spares & Parts range, designed to provide clarity for both homeowners and trade professionals.
Why are shower spares important?
Shower spares are the key to a sustainable and cost-effective bathroom. Instead of replacing an entire shower unit due to a minor fault, a spare part allows you to restore performance for a fraction of the cost. They are essential for stopping leaks, ensuring thermostatic safety, and extending the lifespan of your existing fixtures.
What brands do you stock?
We carry one of the largest selections of spares in the UK. This includes world-renowned "spotlight" brands such as Mira, Grohe, Triton, Aqualisa, and Bristan, as well as specialist brands such as Croydex for seals and Vado. We also stock exclusive trade-trusted parts from iflo that you won’t find anywhere else.
What are the most common spares needed?
The most frequently requested items are thermostatic cartridges (to fix temperature issues), replacement shower hoses, handsets, and shower screen seals. We also see high demand for riser rail brackets and flow cartridges, which often wear out through daily use.
Do you offer bulk discounts?
Yes! For our trade customers, we offer Bulk Savings on many essential spares and consumables. By opening a City Plumbing Trade Account, you can access personalized trade pricing and volume discounts that help you keep your "van stock" topped up at a lower cost.
Are your shower parts suitable for large-scale projects?
Absolutely. We support everyone from independent plumbers to national contractors. Our spares are trade-grade and designed to meet the rigorous demands of commercial settings, such as hotels, housing developments, and public facilities, where durability is non-negotiable.
Do you provide tech specs for each product?
Yes. We understand that precision is vital when matching a spare part. On our website, you will find detailed technical specifications, including manufacturer part numbers, dimensions, and compatibility dates (e.g. "1990–2003"). Our in-branch experts are also on hand to help you identify a part if you aren't sure which version you need.
Do you offer next-day delivery?
We certainly do. We have over 20,000 spares available for Next Day Delivery when ordered by the cut-off time. Alternatively, you can use our Click & Collect service to pick up in-stock items from your local branch in as little as one hour.
