Thetford Aqua-Magic Style Plus: 34429–34438 RV Toilet Parts

The Thetford Aqua-Magic Style Plus combines a ceramic bowl, polymer base and residential-style soft-close seat. Its four model numbers identify the finish and whether the toilet is high or low profile. The Style Plus uses a distinct pedal cable and water-valve drive arrangement; use its own diagram for service parts rather than assuming the older Style II or lighter Residence components fit.

Select by colour, height and floor space

For both profiles, Thetford's dimension sheet lists a 16-inch overall width and 21¹³⁄₁₆-inch depth. That longer footprint matters where the bathroom door, shower partition or vanity sits close to the toilet. Measure the actual flange location and surrounding clearances before replacing a different model.

Find the correct Style Plus replacement number

Thetford's current Style Plus exploded drawing identifies each item with a numbered callout. Several parts are different from the Style II, especially the waste-ball seal, water valve, foot pedal and cable. Match the finish and exact callout shown below.

Checking the fit and operating mechanism

1. Compare the original model number, height and colour with the four photographs above.
2. Confirm the floor mounting and fresh-water connection locations, including clearance for the pedal to move freely.
3. Turn off the water supply before inspecting valve and pedal components.
4. Match the service part to Thetford's callout; some older finishes and shroud variants may have limited replacement availability.

If your model is the smaller Aqua-Magic Style II, use its own parts guide. For a lightweight polypropylene-bowl alternative, see Aqua-Magic Residence. These toilet families do not all use the same waste-ball seals or valves.
