Types of Sinks and Their Installation Needs
The world of sinks is surprisingly varied. The type you choose will have a direct impact on the installation process and cost. Understanding the differences will help you in your conversation with potential fitters.
Inset Sinks (Top-Mount)
These are the most common type of kitchen sink in the UK. They have a visible rim that sits on top of the work surface, and are "dropped in" to a hole cut in the worktop. They are compatible with almost any worktop material, especially laminate. While the installation is the most straightforward of all sink types, achieving that perfect, long-lasting waterproof seal is still a job best handled with care and experience.
Undermount Sinks
Undermount sinks are fitted beneath the worktop, creating a sleek, seamless look that makes wiping crumbs straight into the sink incredibly easy. They are typically paired with solid surfaces like granite, quartz, or solid wood, as the exposed edge of the worktop cutout needs to be polished and waterproof. Installation is a highly skilled job. It requires precise cutting of the worktop, and the sink must be secured with strong adhesives and support brackets. This is not a DIY task.
Belfast and Butler Sinks
These large, deep ceramic sinks make a stunning traditional or modern-country style statement. They are defined by their exposed front panel. A Belfast sink has a weir overflow, whereas a Butler sink traditionally does not. Due to their immense weight, especially when full of water, they must be installed on a dedicated, reinforced base cabinet. Levelling and sealing them correctly is a job for a professional who has experience with these specific types of sinks.
The Kitchen Sink Replacement Process: What to Expect
A professional fitter will follow a logical process to ensure the job is completed efficiently and to a high standard. Knowing the steps can help you understand what's happening in your home.
- Preparation and Disconnection:The fitter will start by clearing the base cabinet under the sink and turning off the water at the isolation valves or the mains stopcock. They will then disconnect the hot and cold water pipes and the waste trap.
- Removing the Old Sink:The clips holding the sink to the underside of the worktop will be released, and the silicone seal will be carefully cut. The old sink can then be lifted out.
- Preparing the Worktop:The fitter will thoroughly scrape away all the old silicone and clean the worktop surface to ensure the new seal will be completely effective. If the hole needs adjusting, this is when it will be done.
- Fitting the New Sink:The new taps will usually be fitted to the sink before it is placed into the worktop. The fitter will then apply a fresh bead of sanitary-grade silicone around the edge of the cutout, lower the new sink into place, and secure it with its mounting clips.
- Connecting the Plumbing and Taps:The new tap tails will be connected to the hot and cold water supply, and a new waste and trap will be fitted and connected to your drainage pipe. Any associated appliances like dishwashers will be reconnected.
- Testing and Tidying Up:This is a crucial final step. The fitter will turn the water back on and thoroughly check every joint and seal for leaks. They will test both hot and cold taps and fill the sink to test the waste and overflow. Finally, they will clean up their work area, leaving your kitchen tidy.
