RV Bathroom Sink Size Guide: JR Products & LaSalle Bristol

Replacing an RV bathroom sink starts with the opening in the countertop. The outside rim, the opening underneath it and the depth of the bowl are different measurements. A sink that appears to be the same size in a product photo can still require a different cutout, faucet position or drain connection. Use this guide to compare two JR Products molded lavatory sinks with two compact stainless-steel LaSalle Bristol designs.

Molded rectangular versus stainless round and oval

JR Products molded rectangular sinks95351 (white) and 95361 (parchment) share a 14⅞-inch-wide, 12⅜-inch front-to-back outside profile with a 6-inch overall height. The manufacturer specifies a 14¼ × 11½-inch countertop cutout and supplies a tail flange, rubber stopper, mounting clips and screws.
LaSalle Bristol stainless sinks13TF0105 is a 10½-inch round, 4-inch-deep, 20-gauge sink with a 2-inch centred drain opening. 13TF1310 is an oval 13¼ × 10½-inch, 5-inch-deep, 21-gauge sink with a 1¾-inch centred drain. Neither has integrated faucet holes.

Do not cut from the outside dimensions. For JR Products 95351 and 95361, the outside width is 14⅞ inches while the manufacturer-specified cutout width is 14¼ inches. For LaSalle Bristol 13TF0105 and 13TF1310, the listed measurements describe the sink overall; no approved countertop cutout dimensions were verified for these exact versions. Use the manufacturer's specific installation drawing or a correctly measured existing installation before cutting.

How to measure for a replacement RV sink

  1. Measure the opening, not just the visible rim. Note the maximum left-to-right and front-to-back cutout dimensions. For a round opening, measure the true diameter in multiple directions.
  2. Measure rim coverage and available countertop area. The new flange must fully cover the cutout with adequate supporting material around it. Do not assume similar shapes have matching footprints.
  3. Check vertical clearance. Confirm the bowl depth, drain outlet, cabinetry, shelves and any nearby drawer before ordering. The JR Products six-inch dimension is its overall sink height; the LaSalle Bristol figures are published bowl-depth measurements.
  4. Match the drain assembly. LaSalle Bristol lists a 2-inch drain for 13TF0105 and a 1¾-inch drain for 13TF1310. Confirm your existing strainer and plumbing diameter; do not assume either drain fitting is included.
  5. Confirm the faucet arrangement. Both stainless-steel models are listed with zero integrated faucet holes, requiring an appropriate separate faucet location. For JR Products, inspect the actual faucet holes and existing supply connections before choosing a replacement.
  6. Check what's supplied. JR Products lists mounting clips, screws, a 6-inch tail flange and a 4-inch rubber stopper with the two molded sinks. The four-inch figure describes the stopper's length, not a four-inch drain opening.

Which sink works with an existing countertop?

If your RV has the JR Products-style rectangular opening of 14¼ × 11½ inches, 95351 and 95361 are the two colour choices with that published cutout. If the countertop has a small round or oval opening, compare its actual geometry with the manufacturer drawing for the corresponding LaSalle Bristol MPN. Never treat a nominal “10-inch” product title as the actual cutout diameter.
