Are Bathroom taps a Standard Size - Comprehensive Guide

Table Of Contents:


When renovating or updating your bathroom, one key question many homeowners and designers face is whether bathroom taps follow a standard size.

Understanding tap sizes is crucial for ensuring compatibility with your sink, bath, or basin, and for achieving a seamless installation process.

This guide delves into the nuances of bathroom tap sizes, offering insights to help you make informed decisions for your bathroom updates with Tapron UK’s extensive collection.

Understanding Tap Sizes

Bathroom taps come in various designs, each with its specific dimensions. However, there are some general standards in the industry that can guide you when selecting your new taps.

Basin Taps

Basin taps are typically designed to fit standard basin tap holes, which are about 35mm in diameter. This size can slightly vary depending on the design and brand. For instance, monobloc basin mixer taps usually require a single hole of this standard size, whereas pillar taps might need two holes spaced according to the basin's design.

Bath Taps

Bath taps, including bath mixer taps and bath fillers, often have a larger fitting size due to the higher water flow rate required. The standard size for bath tap holes is generally around 180mm from center to center, though this can vary based on the design and the manufacturer.

Wall-Mounted Taps

Wall-mounted taps require careful consideration regarding placement and height relative to the basin or bath. While there isn’t a strict standard size for the tap itself, the positioning is crucial for functionality and aesthetics. Consulting with a professional during planning can ensure optimal placement.

Measuring for Tap Installation

To ensure the taps you choose will fit your basin, bath, or shower setup, accurate measurements are vital. Here are some tips:

  • Measure the Diameter of Existing Holes: For replacements, measure the diameter of the existing holes in your sink or bath. This ensures the new taps will fit without the need for additional drilling.

  • Check the Spacing for Pillar Taps: If you’re opting for separate hot and cold taps, measure the distance between the centers of the two holes.

  • Consider the Tap’s Reach: Especially important for basins, ensure the spout will reach far enough into the basin for practical use without splashing.
