Install a Shower Tray

Trade: Plumber

⭐ Introduction

Installing a shower tray is a common plumbing job that provides a sturdy, watertight base for your shower enclosure. You might need to install a new tray when fitting a new shower, replacing a damaged or leaking tray, or upgrading your bathroom to improve accessibility or style.

A correctly installed shower tray prevents water damage by channeling water to the drain and away from the floor and walls. This job usually requires a plumber because it involves precise fitting, plumbing connections, and often waterproofing under building regulations.

🔧 What the job involves

Installing a shower tray involves several key tasks:

  • Removing the old tray (if applicable), including disconnecting waste pipes and checking the floor surface.
  • Preparing the floor to ensure it is level and structurally sound to support the tray.
  • Fitting the new tray, ensuring it is completely level and securely fixed in place.
  • Connecting the tray to the waste plumbing, making sure all joints are watertight.
  • Sealing around the tray’s edges with silicone or waterproof sealant to prevent leaks.
  • Depending on the tray type (acrylic, stone resin, or tiled), the installation method will vary slightly.
  • Ensuring compliance with Part P of the Building Regulations for electrical safety if any electrical components are nearby.
  • Testing the completed installation to check for leaks and proper drainage.

  5. Completion: The plumber cleans up and explains any care tips. You receive any necessary paperwork, such as guarantees or Building Regulation compliance certificates if applicable.
  6. Aftercare: You keep documents safe and arrange any further plumbing or tiling work needed.

📊 What affects the price

  • Accessibility of the bathroom and space constraints
  • Condition of existing plumbing and drainpipes
  • Complexity of the tray design (e.g. curved or low-profile trays)
  • Whether floor repairs or levelling are needed
  • Building Regulations compliance or certification requirements
  • Location in the UK (higher labour rates in London/South East)
  • Urgency or short-notice bookings

⏱ How long does it take?

  • Simple replacement: 3 to 5 hours.
  • Installing a new tray on a prepared floor: 4 to 6 hours.
  • Complex installs involving floor repairs or unusual plumbing: up to 1 or 2 days.
  • Additional tasks such as tiling or building shower enclosures will add more time.

🏠 Can you DIY it?

While it’s possible for experienced homeowners to install a shower tray themselves, it is not recommended for most. Key reasons include:

  • Ensuring the floor is correctly level and stable.
  • Connecting waste plumbing correctly to avoid leaks and blockages.
  • Complying with UK Building Regulations and plumbing standards.
  • Achieving a proper waterproof seal.
  • Correct disposal of old tray and waste materials.

Hiring a qualified plumber means less risk of water damage or costly mistakes. If electrical work or wall tiling is involved, professionals are highly recommended.

💰 Typical UK price range

A typical shower tray installation with a qualified plumber costs around £350 to £600 excluding VAT. More complex jobs with floor preparation or bespoke trays could be £700 or more. Prices vary depending on region and specific circumstances.

VAT at 20% is usually added unless the work is part of a full property refurbishment or certain home improvements qualify for reduced VAT rates.

✅ Handy tips before you start

  • Clear the bathroom area to provide good access for the plumber.
  • Make sure the floor under the tray is dry and free of mould.
  • Ensure you know where your water stopcock is in case of emergencies.
  • Keep all paperwork such as quotations, invoices, and certificates for future reference or warranty claims.
  • Ask your plumber about aftercare, such as re-sealing the tray edges periodically.
  • If you’re upgrading your bathroom, confirm whether you need Building Regulations approval.
  • Consider any compatibility with your shower enclosure to avoid extra fitting work.

By preparing well and choosing a qualified plumber, your new shower tray installation should be smooth and worry-free.
