Find the real bottleneck
Write down the order of a normal busy morning without trying to make it ideal. Note who brushes teeth, washes, shaves or uses the mirror, and which tasks can happen outside the bathroom. Repeat for a quieter day so an occasional rush does not become the only design criterion.
If one person is using the shower while another waits outside a private bathroom, adding a second bowl may not remove the queue. If two people already share the room and both need the basin, a double arrangement may address the actual problem. Treat the timetable as a household conversation rather than a precise prediction.
| Observation | Question to resolve |
|---|---|
| Two people need running water together | Can both stand and move at the proposed washplace? |
| One person only needs a mirror | Would another mirror position solve the conflict? |
| Toiletries cover the top | How much landing space remains around two bowls? |
| One basin is usually unused | Is a larger single wash area more useful? |
Test the two-person position
Mark both bowl centres from the exact drawing and stand at the proposed positions. Check elbows, drawer access and the route behind someone using the basin. Do not infer comfortable spacing by halving a unit's nominal width; bowl shapes and margins differ.
Include the mirror size and sightlines in the trial. Two separate mirrors may create different views from one wide mirror, but either arrangement needs to suit the users and the surrounding lighting.
Compare complete assemblies
List both bowls, taps, wastes, cabinet and top as one proposed assembly. Ask what is included and which compatible components are separate. Saneux's UNI 120cm four-drawer unit, for example, is specified for its matching two-bowl basin; that product relationship does not establish compatibility with any basin of a similar width.
The countertop-versus-inset comparison helps you judge the height and cleaning edges of the proposed bowls. Ask the installer to confirm the water and waste arrangement for two basins rather than assuming the existing single-basin connections are sufficient.
Write the reason for one bowl or two
A useful brief might say: 'Two people wash at the same time most weekdays; we want separate personal storage and enough shared landing space.' Another might say: 'Only one person uses water at once; we prefer more clear worktop.' Neither needs a claim that one format is universally better.
Take the routine sheet and a measured wall width to your showroom appointment. Check a real example where possible, and keep the choice provisional until the full assembly and user movement have been reviewed.
