How To Manage Your Bathroom Renovation Budget?


With all these potential costs and eventualities, sticking to your initial budget can feel like a daunting task. But with careful planning and some flexibility, it's entirely possible to see your project through without breaking the bank.

Beware of "Scope Creep"

Scope creep is when a project grows beyond its original objectives in size, cost, or complexity. To avoid this, make a list of "must-haves" and "would-likes" at the start of your project and stick to it.

Allocate a Contingency Fund

A good rule of thumb is to set aside an extra 10-20% of your total budget for unforeseen expenses that might crop up during the project.

Choose Quality Over Quantity

While it can be tempting to cut costs with lower-quality materials, investing in quality fixtures and fittings can save you money in the long term. High-quality items are typically more durable and have longer warranties, minimising potential repairs and replacements.

DIY Where Appropriate

Simple tasks like painting, light fixture installation, and even some tiling can be done yourself with the right knowledge and tools, saving you on labour costs.

Plastering Decisions: The Right Choice for Your Bathroom


Plastering is a critical part of bathroom renovation. Moisture and air quality are top concerns, making the right choice of plaster crucial for the health of your bathroom and the longevity of your renovation.

Types of Plasters for Bathrooms

Two common options are Multi-finish plaster, which is versatile and strong against dampness, and Tough Coat, specifically designed for areas prone to high moisture levels, such as bathrooms.

The Cost of Plastering
