1. Maintain the existing layout since moving plumbing and electrical fixtures can significantly drive up the cost of a bathroom remodel. Consider sticking with your current strategy if it can be executed successfully and is reasonable to do so. This will help you save money on labour and supplies.
 
2. Utilize materials that are low-cost: Laminate countertops, vinyl flooring, and ceramic tile are just a few examples of the economical materials that are accessible for use in bathroom renovations. If you use these materials, you might be able to save a lot of money without sacrificing the look or the quality of your work. 

3. Repurpose existing fittings: Rather than investing in brand new fittings, give some thought to repurposing the ones you already have if they are in usable condition. This may help you save money on the individual expenses of the fixtures as well as the fees associated with the installation. 

3. Compare prices: Compare the costs of labour, supplies, and furniture among a number of different vendors and contractors to see which offers the best value.
Consider performing part of the work yourself if you're handy around the house and don't mind putting in the effort. You may be able to reduce the amount of money you spend on labour by doing this; nevertheless, you will need the appropriate knowledge, abilities, and tools for the job.

4. Put in fixtures with a low water flow: Installing low-flow showerheads, toilets, and faucets can cut down on the amount of water you use and consequently minimise your monthly water bill. 

5. Avoid going overboard with the design. Stay away from flashy design elements that could end up driving up the cost of your project. Keeping your design straightforward and functional will help you save money. 

6. Lighting: If you want to lower the amount of money you spend on electricity, use lighting fixtures that have a high energy efficiency rating and natural light sources.
It may be more cost-effective to replace a bathtub or shower than to refinish it because replacing it can be expensive, and restoring it may also lessen the need for installation. 

7. Your needs can be prioritised by directing the majority of your spending money into the aspects of the bathroom that are the most important. If you take the time to prioritise your requirements, it will be much simpler for you to make intelligent financial decisions. 

8. When looking for ways to minimise costs, it is essential to keep in mind that doing so may need compromising on aspects such as quality or design. It is always recommended to strike a balance between the expense and the design of a project.
