How much does a bath cost?
At Buildiro, we prioritise offering our customers accurate and dependable information. When contemplating the acquisition of a bathroom suite, it’s crucial to remember that bathtubs are generally not part of the package and will necessitate a distinct purchase. The price of a bathtub fluctuates based on several factors, including the chosen material and dimensions. For those seeking an economical choice, thinner acrylic tubs frequently present the most budget-friendly option and can be easily integrated into a framework, finalised with a separate bath panel.
How much does a new shower cost?
If you want to understand how to select a shower, consider electric showers. These are the most budget-friendly choice and suitable for individuals aiming for a swift and cost-effective bathroom upgrade.
Electric showers are connected solely to the mains cold water supply and heat water as needed. Consequently, they may achieve a different power level than power showers or those reliant on stored hot water. However, opting for a higher kilowatt rating can enhance their performance.
On a positive note, electric showers are cost-effective in operation, their installation is uncomplicated, and they start at approximately £40.
Alternatively, bath/shower mixers also serve as a viable option for those seeking to manage their bathroom renovation expenses, with prices starting at £30.
Does the bathroom add value to the house?
Updating your bathroom can increase your home’s value by 4-5%. A new bathroom provides a peaceful space to unwind after a long day. It’s a smart investment for personal use or resale value.
