In short
Ask whether a thick-looking edge is solid material or a built-up detail. Confirm the appearance, joins, support and price of the exact construction.
Start with the profile you want to see
Look at the worktop in relation to door proportions, handles and the height of nearby surfaces. A quieter edge can let a strong pattern stand out; a more substantial profile can change the balance of the whole kitchen.
Take your preferred image as a conversation starter, then ask the fabricator how it can be achieved in the chosen surface. Do not infer thickness or construction from a photograph alone.
Compare the actual available options
Available thicknesses depend on the product and supplier. Ask for those offered for your selected colour and finish, then check the implications for sinks, hobs, supports and existing cabinets. Nominal dimensions should be confirmed on the final specification.
For a replacement, consider the height of the old surface and where it meets tiles or walls. Changing it may create an additional making-good task.
Understand the edge detail
Ask to see a finished edge sample rather than selecting only from profile names. Different fabricators may use different terminology. A simple eased edge, a curve and a mitred build-up each need a clear drawing or sample to establish the intended result.
On porcelain and sintered surfaces, ask how the edge relates to the decorated face. On a veined slab, discuss how any joint or built-up section will affect the pattern.
Consider corners, openings and seating
Discuss corners on walking routes, sink edges and any seating overhangs. Ask the fabricator to approve the detail for the chosen material and to specify the support needed. A thicker visual edge does not automatically establish the structural capacity of a surface.
If you want drainer grooves or a particular sink reveal, agree those details alongside the edge. They affect the fabrication work and the appearance around the most frequently used part of the kitchen.
Put the decision into the quote
- Exact product, finish and nominal thickness.
- A sample or drawing of the visible edge profile.
- Locations of mitred or built-up sections.
- Treatment of corners, sink openings and exposed ends.
- Support design agreed with the appropriate installer.
Bring these decisions to the templating stage and compare them consistently when assessing quotations.
