Getting the Correct Drop in Sink Size for Your Kitchen
Looking to upgrade your kitchen with a new drop-in sink? Choosing the right size is critical for a smooth installation and years of functionality. Take precise measurements and evaluate your space needs before selecting a model.
We'll also explore recommendations for allowing adequate room for the sink basin, faucets, backsplashes, and more.
Keyword Research and Analysis
Let's start by getting familiar with some terminology. Drop-in, or self-rimming, sinks feature a lip around the outer edges. This rim rests on top of the countertop cutout. Clips underneath affix the sink in place after lowering it into the hole.
These models contrast undermount sinks installed from below the counter with liquid silicone. The lip on a drop-in sink can collect dirt but allows for easier installation. They also cost less than undermount.
Standard kitchen sink sizes range from 22 to 48 inches in length. Depths are commonly 8 to 10 inches, extending from the countertop to the bottom interior. The width measurement spans the back edge to the front corner edges.
Common Drop-In Kitchen Sink Sizes
- 22 inches
- 26 inches
- 30 inches
- 33 inches
- 48 inches
Knowing typical dimensions helps narrow options. But first, carefully measure your existing space.
Measure Countertop Opening
Start by measuring the countertop hole if replacing an existing drop-in sink. This reveals the maximum dimensions for the new sink and is simplest.
Tools Needed
- Tape measure
- Pencil and paper
- Flashlight
- Cloth measuring tape
Use a sturdy steel tape measure for this task. A cloth measuring tape also helps estimate tighter spaces. Have a flashlight handy to peer into darker cabinet corners.
Techniques for Precision
Removing the old sink first allows full visibility. Thoroughly clean the countertop hole and cabinets before starting.
Insert the tape measure into the opening and stretch to the furthest back wall. Mark the measurement on paper. Repeat on all sides. For width, measure the left and right edges.
A flashlight illuminates rear corners. Set the tape measure precisely vertical and horizontal during measuring for accuracy.
Remember that a drop-in sink needs 1-2 inches of countertop landing area around the basin. Account for the surrounding lip size so the new sink fits properly.
Calculate Cabinet Opening Size
If fully replacing countertops, calculate the cabinet opening size instead. This requires more precision but allows custom-sizing the new sink.
Remove Sink and Measure Carefully
Detach and remove the existing damaged sink to open full cabinet access. Measure across the rear backsplash edge and side walls.
Document the exact width and length. Extend a tape measure diagonally corner-to-corner as a guide.
Account for Plumbing and Electrical
Note any supply lines, P-traps, wire locations, or holes pre-drilled for accessories. Measure and mark their placement to avoid conflicts installing the new sink.
Service access panels on the cabinet exterior may also dictate size limitations.
Record Detailed Dimensions
Tracking all measurements prevents surprises once the new sink arrives. Photographing the empty cabinet also references placement of pipes, wires, and stud locations.
Jot down notes complementing exact sink opening measurements. These help select accurate fixtures and accessories.
Select Appropriate Sink Size
With measurements complete, browse sink options in suitable widths and lengths. Most importantly, match the shape of your opening--either rectangular or curved front.
Evaluate Popular Sizes
Use your notes to narrow suitable models. If the opening exceeds 30 inches, for instance, limit choices to larger 33, 36 or 48 inch sinks.
Consider basin configurations as well. Both single and double bowl styles typically span smaller 22 to 30 inch spaces.
Allow Adequate Clearance
Ensure at least 1-2 inches of countertop space around the sink basin after installation. Without this buffer zone, splashing water may damage surrounding surfaces.
Check that preferred faucets, backsplashes, cutting boards and wash baskets still fit in the remaining areas.
Order Correct Sink and Accessories
Once identifying the ideal sink dimensions from quality brands, order the exact model fitting your documented measurements.
Purchase Matching Fixtures
Include any faucets, soap dispensers, side sprayers, filters, cutting boards, colanders, drain baskets or other accessories in the same order.
Availability often dictates buying together. Plus, bundled shipping saves costs over separate orders.
Verify Dimensions Align
Carefully check listed sink specifications during checkout. Length, width, and depth must match your opening for proper fitting.
If concerned, contact the manufacturer to confirm dimensions satisfy your existing cabinet cutout.
Prepare Cabinet and Countertop
While awaiting delivery, create an optimal foundation for sink installation. Adjust cabinets or wall areas as needed to accommodate.
Ensure Sink Fit
If walls or backsplashes seem obstructively close to the documented measurements, alter or remove portions allowing the planned sink to insert.
Consider hiring a contractor if major structural changes become necessary to widen the area.
Cut New Countertop Hole
For fresh countertop installations, use the sink dimensions as a template for cutting the hole. Allow a 1-2 inch margin around the basin circumference.
Follow manufacturer guidelines for recommended opening sizes per the exact sink model.
Install New Drop-In Kitchen Sink
Once the foundations are solid, excitedly await delivery of the new sink! Install using the manufacturer's included directions.
Test Fit Your New Sink
Unbox carefully to avoid damage. Initially do a dry run only placing the sink centered into the opening. Don't attach anything yet.
Verify straight angles on all sides and that the rim lip sits flush with no significant overhang.
Secure as Directed
If satisfied with the positional test fit, lift back out and flip over. Attach mounting hardware, clips, brackets and supporting frames appropriately.
Follow instructions precisely to ensure lasting security and proper drainage angles.
With the sink re-lowered and firmly fixed, connect drains and supply lines. Confirm fittings are snugly tightened at all joints.
Turn on the water supply and carefully check below for leaks. Verify proper drainage without gurgles as the final step!
