| 1 |
Choose a sink or basin material |
Vitreous china and porcelain-enameled surfaces are nonporous and commonly used for bathroom basins. Solid-surface materials should have a documented repair and refinishing specification. |
Request the written finish warranty, exclusions for chips or impact damage, and replacement-part availability. |
Use non-abrasive cleaner; remove standing water and mineral deposits regularly. Avoid scouring pads that can dull glossy finishes. |
Prefer a nonporous surface with a clear care guide and an accessible replacement or repair process. |
| 2 |
Evaluate faucet body construction |
Look for brass, stainless steel, or a clearly specified corrosion-resistant alloy. A ceramic disc cartridge is generally preferred for repeated handle operation. |
Compare the coverage period for the body, finish, cartridge, and electronic components separately; these terms are often different. |
Clean aerators when flow decreases. In hard-water areas, inspect and descale the aerator approximately every 3–6 months. |
Do not rely on the word “metal” alone; require the specific body material and cartridge type. |
| 3 |
Select a showerhead by flow rate |
For products sold in the United States, WaterSense-labeled showerheads use no more than 2.0 gallons per minute at standard test pressure while meeting spray-performance criteria. |
Check the performance certification and the warranty for spray plates, flow regulators, and removable components. |
Clean rubber nozzles as directed and remove scale before it restricts spray patterns. Do not drill out a flow regulator. |
Balance the certified flow rate with local water pressure and the ability to clean or replace the spray face. |
| 4 |
Compare toilet flushing performance |
A WaterSense-labeled toilet uses 1.28 gallons per flush or less and must meet EPA flushing-performance requirements. Verify the tested flush performance rather than judging only by flush volume. |
Confirm warranty coverage for the ceramic body, flushing mechanism, fill valve, and seat because component terms may differ. |
Inspect the flapper or flush valve when water cycles continuously. Replace worn seals promptly to prevent unnecessary water loss. |
Choose the lowest verified flush volume that meets the required performance and has readily available service parts. |
| 5 |
Assess exposed metal finishes |
Compare finish test information, such as resistance to corrosion, chemicals, humidity, and abrasion. PVD finishes may offer strong surface resistance, but performance depends on the coating system and test method. |
Ask whether the finish warranty covers peeling, flaking, discoloration, and corrosion, and identify cleaning products excluded from coverage. |
Dry the surface after use and avoid chlorine bleach, abrasive powders, and acidic cleaners unless expressly approved for that finish. |
Select finishes with documented test results and care instructions that match the household’s cleaning routine. |
| 6 |
Check water-contact metal quality |
For stainless steel, grades such as 304 and 316 are commonly specified; 316 generally provides greater resistance to chloride exposure because it contains molybdenum. Confirm compliance with applicable potable-water requirements. |
Request material declarations, plumbing approvals, and warranty exclusions related to water chemistry or improper installation. |
If water is highly corrosive or chlorinated, inspect connections and valves periodically for pitting, leaks, or green and white deposits. |
Use a documented alloy and approved plumbing components rather than selecting solely by surface appearance. |
| 7 |
Measure installation stress and load |
Confirm that the mounting hardware, countertop, wall carrier, or substructure is rated for the fixture’s operating load. Wall-hung fixtures require properly designed concealed supports. |
Keep installation instructions and verify whether damage caused by unsupported loads, overtightening, or movement is excluded. |
Check mounting nuts, brackets, and exposed sealant during routine cleaning; movement is an early warning sign of failure. |
Reject a fixture if the installation system lacks a clear load requirement or compatible reinforcement detail. |
| 8 |
Plan for hard-water conditions |
Mineral scale commonly contains calcium carbonate and can restrict aerators, cartridges, shower nozzles, and flush valves. Smooth, removable components are easier to maintain. |
Verify that descaling procedures do not void the warranty and that replacement cartridges, screens, and seals can be ordered separately. |
In areas with visible scale, inspect flow components every 3–6 months and follow the manufacturer’s approved descaling method. |
Prioritize tool-free screens, removable spray plates, and serviceable cartridges over decorative complexity. |
| 9 |
Review seal and hose specifications |
Look for certified supply hoses, quality elastomer seals, and corrosion-resistant connectors. Flexible hoses should not be sharply bent, twisted, or placed under tension. |
Record the warranty term for hoses and seals separately; these consumable parts may have shorter coverage than the main fixture. |
Inspect visible hoses and connections for bulges, rust, dampness, or mineral trails at least twice a year. |
Choose replaceable, certified connections and leave enough access for inspection without removing the fixture. |
| 10 |
Calculate lifetime maintenance cost |
Compare the number of moving parts, availability of seals and cartridges, water consumption, and access to service points. A durable fixture should be repairable rather than disposable. |
Prefer a written warranty with clear claim procedures, labor limitations, proof-of-purchase rules, and a stated spare-parts support period. |
Create a simple annual checklist: leaks, flow reduction, loose mounting, finish damage, seal condition, and operation of shutoff valves. |
Select the option with the lowest credible total cost of ownership, not necessarily the lowest initial purchase price. |
