TOTO TBW01012U4#CP – Frequently Asked Questions
1) Will the TOTO L Series 4 inch showerhead thread onto a standard shower arm?
The connection is G 1/2, which is the standard half-inch shower arm thread used on residential and commercial shower arms, so it threads onto an existing arm without an adapter. TOTO lists the TBW01012UV1 shower arm as the matching arm, sold separately. No valve comes with the showerhead, so if you are replacing a valve as well as the head, that is a separate order.
2) Does this TOTO showerhead meet California water efficiency rules for a multifamily or hotel retrofit?
Yes. The L Series 4 inch showerhead runs a maximum flow rate of 1.75 GPM and is WaterSense certified, CEC compliant, and CALGreen compliant, which is the combination California projects are checked against. For a fleet retrofit across units, that means one part number clears the spec on every opening rather than mixing compliant and non-compliant heads.
3) What is the difference between the TOTO TBW01012U4 and TBW01013U4 showerheads?
Spray settings. The TBW01012U4#CP is a single spray head, and the TBW01013U4#CP gives five spray settings. Both are 4 inches across the face and 2.6875 inches high, both in polished chrome, both 1.75 GPM. If you are standardizing across rental units, the single spray head has nothing for a tenant to knock out of adjustment; the five setting head is the one to pick where residents expect a choice.
4) What do I need to order to finish a TOTO L Series showerhead install?
Plan on the shower arm and the valve as separate lines. No valve is included with the head, and TOTO pairs it with the TBW01012UV1 arm, sold on its own. If the existing G 1/2 arm and escutcheon are sound, the head is a direct swap and you order nothing else.
5) How much room does a 4 inch TOTO round showerhead take off the shower arm?
The head measures 4 inches across and 2.6875 inches high on the TBW01012U4#CP and TBW01013U4#CP, and 4.0625 by 2.875 inches on the TBW03001U4#CP. At about a pound, it puts no real load on the arm or the drop ell behind the wall, which matters on older plumbing where the arm threads are the weak point.
6) Which TOTO showerhead holds up best in hard water?
All four versions use rubber nozzles, which flex when you wipe them and shed limescale instead of clogging the way brass or plastic jets do. In a hard water building that is the difference between a head you wipe down during a turnover and one you replace. Polished chrome is the only finish offered, across both the Classic and Modern styles.
7) Classic or Modern style on the TOTO 4 inch round showerhead, which should I pick?
Both are round polished chrome and both run 1.75 GPM, so it is an appearance and size call, not a performance one. Classic covers TBW01012U4#CP (single spray) and TBW01013U4#CP (five spray) at 4 by 2.6875 inches. Modern in five spray is TBW03001U4#CP, slightly larger at 4.0625 by 2.875 inches, and Modern is also offered in single spray. For a building where heads need to look alike across units, pick one style and stay on it.
8) Is a 1.75 GPM showerhead going to feel weak in an apartment with low water pressure?
1.75 GPM is below the 2.5 GPM federal ceiling, so it is a low flow head by design and pressure at the head matters more than on a 2.5. The rubber nozzles concentrate the spray to hold up the feel, and the five setting versions (TBW01013U4#CP and TBW03001U4#CP) let a resident pick a tighter pattern where supply pressure is marginal. On a building with known low pressure, the five setting head is the safer specification.
