Short answer
For a Jack and Jill bathroom remodel in Highland Park, hire one firm that both designs the room and runs the construction, and that knows the Town of Highland Park issues its own permits. Chateau Concepts does both: Jan Revels, ASID Allied, draws the plan and builds it as general contractor. The key layout decision is whether to separate the sinks from the toilet and the tub or shower, so two children can get ready at the same time with privacy.

Which layout works best between two bedrooms?
Start with the morning routine. Can a child brush teeth while a sibling showers? Can someone use the toilet without closing off both sinks? Does either bedroom look directly into a private area?
These questions distinguish the common layouts. We compare them against the existing plumbing and the space available, including any closet area that could be borrowed. More partitions help only when the resulting rooms remain comfortable.
Comparing the three common Jack and Jill layouts
| Layout | What it needs | Privacy | Best fit by age and routine | Watch for |
|---|---|---|---|---|
| Shared room with a door from each bedroom | A complete bathroom with workable paths from both entrances | The entire room becomes private when occupied | Young children with adult help; older children who can take turns | Both doors need a locking routine; bathing blocks sink access |
| Shared double-vanity room with toilet and tub/shower behind an interior door | Enough space for separate vanity and wet areas, including the interior door | Someone can use a sink while the enclosed area is occupied | Children growing into teenagers who need overlapping routines | The wet room needs comfortable fixture clearances |
| Separate vanity alcove for each bedroom, with a shared toilet and tub/shower room between | Space for an individual vanity zone at each bedroom and a shared central room | Personal grooming stays separate; bathing and toilet use remain shared | Children and teenagers who benefit from clearly assigned space | More cabinetry and plumbing coordination; central-room locks need careful planning |
What this means for you: the strongest choice is the one that fits the house and supports actual routines. Separate sink access can reduce morning conflicts, but forcing it into a cramped plan can leave every area harder to use.
For many families, a shared vanity room with an enclosed toilet and bathing area is a useful starting point. It keeps shared grooming space available while protecting privacy. Separate vanity alcoves offer clearer ownership when the bedrooms and plumbing arrangement support them.
A single shared room can still work well when space is limited. Give each child assigned storage and resolve the door routine before construction. Our approach to bathroom remodeling in the Park Cities starts with those practical decisions.
How should doors and locks work?
Door placement controls circulation, privacy and usable wall space. A bathroom may look generous until bedroom doors, cabinet drawers and the shower door are shown open.
We recommend testing the plan in this order:
- Trace access from each bedroom. Check whether either route passes directly beside the toilet or through the other child’s grooming space.
- Show every door open. Include vanity drawers, linen storage and the bathing enclosure.
- Choose the privacy boundary. Decide whether locking closes the whole bathroom or only the toilet and bathing room.
- Establish the unlocking routine. Everyone must understand which doors get locked and released after use.
Swing doors make their operating space clear, but can compete with fixtures and storage. Pocket doors can recover floor space where the wall cavity can accept them. Confirm that plumbing, wiring, blocking and proposed cabinetry will not conflict with the pocket.
Choose bathroom privacy hardware that can be released from outside in an emergency. With bedroom entrances at opposite sides, a child can unlock the exit they use and forget the other entrance. Test the routine with the family; hardware alone does not resolve it.
A third door to the hall can provide guest access without sending visitors through a bedroom. It also takes wall space and adds another privacy decision. Include it only when guest access is a real need and the plan can accommodate it comfortably.
How much room do two sinks and comfortable clearances require?
Two sinks are useful when both children can stand, move and open drawers without crowding each other. A double vanity that consumes the room’s circulation space is a poor trade.
The following figures distinguish typical minimum clearances from more comfortable planning targets. They guide layout discussions; the project’s applicable requirements still need confirmation.
Dimensions to test before choosing fixtures
| Feature | Typical minimum or standard | More comfortable planning target |
|---|---|---|
| Clear floor space in front of a fixture | 21 inches, typical minimum | 30 inches |
| Toilet centerline to wall or fixture | 15 inches, typical minimum | 18 inches |
| Toilet compartment width | 30 inches, typical minimum | 36 inches |
| Shower interior | 30 × 30 inches, typical minimum | 36 × 48 inches or larger |
| Distance between sink centerlines | 30 inches, standard | 36 to 42 inches |
| Double vanity width | 72 inches, standard | 84 inches or more |
| Clear floor in front of vanity | 30 inches, standard | 36 to 42 inches |
| Vanity height | 32 inches, standard; 30 inches for children | 34 to 36 inches for adults |
What this means for you: use the comfortable column to test how the room will feel as the children grow. These dimensions work together: a wider vanity still needs standing space, and an enclosed toilet still needs a usable approach.
A child-height vanity is about 30 inches; most adults are comfortable at 34 to 36. Because the cabinetry will outlast childhood, we usually favor a height the children grow into, with a step stool that lives in the room for the early years. In the Jack & Jill bathroom shown at the top of this page, the two sinks have a lower sit-down counter with a knee space between them, which gives a teenager somewhere to get ready without holding up a sink.
Measure usable counter space as well as sink spacing. Each child needs somewhere to set daily items without covering the entire counter. Custom vanities help when the room width does not match stock sizes, which is common in older homes.
Our guide to how to plan a bathroom remodel explains the broader clearance decisions.
In a shared bathroom the plan decides everything: where the doors swing, whether the plumbing moves, and whether two children can use it at once. Jan draws it to scale first, so the layout is settled before anything is ordered.
What should stay right from age seven to seventeen?
Build the permanent room for growing independence. Our kids’ and teen bedroom design approach applies here: fix layout, storage and lighting, then let color, hardware and textiles follow the child’s age.
Assign storage by child and by task. Daily items belong in a top drawer notched around the plumbing trap, where they can be reached without searching behind bottles. Separate drawer areas make shared counters easier to keep clear.
Plan a deep drawer for a hair dryer and corded tools, with an outlet inside the cabinet. Coordinate the electrical arrangement during design and follow the appliance’s use and storage instructions. Teen grooming needs should influence the cabinetry before it is built.
Bath towels need about 14 inches of depth in a linen closet or tall cabinet. Provide individual towel locations as well as space for clean supplies. Put blocking in the walls for towel bars, grab bars and wall-hung fixtures while the walls are open.
Lighting should come from both sides of the mirror, supported by ambient light and a low-level night light. Younger children need a reassuring nighttime route; teenagers need useful grooming light. Slip-resistant floor tile supports everyday use at both stages.
Keep at least one bathtub somewhere in the house for young children and resale. Before replacing this bathroom’s tub, review shower or tub: which to keep against the rest of the home.
Our bathroom vanities and storage guide develops these cabinet decisions further.
What is different about remodeling in Highland Park?
Most Highland Park houses date from the 1910s through the 1930s and have been altered before. Older Park Cities homes often have fewer, smaller bathrooms than families expect today. The existing arrangement needs careful measurement before a new plan is drawn.
Enlarging a bathroom usually means borrowing from a bedroom or closet rather than adding on. Borrowing 18 inches from an oversized closet can turn a cramped bathroom into a good one. Evaluate the remaining closet at the same time; bathroom improvements should not leave the bedroom without useful storage.
Next, establish whether the plumbing moves and what foundation lies beneath it. A pier-and-beam house provides crawl-space access for comparatively straightforward rerouting. A slab requires cutting concrete, and post-tension slabs require care around the tensioning cables.
Highland Park issues its own permits and conducts its own inspections. University Park operates separately from Highland Park and Dallas. Preston Hollow is inside the City of Dallas, so permits go to the City.
The Town’s Building Inspection page says permits are required before construction begins and that inspections must be obtained before work is concealed. In a bathroom, the concealed work is the plumbing in the walls and the shower assembly behind the tile. When Chateau Concepts is the general contractor, we file the applications with the Town as part of running the job, and the Town’s review time goes into the schedule from the start.
Our planning for home remodeling in Highland Park accounts for the older house, available space and local review. A North Dallas address should receive the same careful jurisdiction check before permit planning begins.
What waterproofing and ventilation should you insist on?
Layout, waterproofing and ventilation determine whether the bathroom serves well for decades. Finishes matter, but they sit on top of those fundamentals.
For the wet area, establish cement or foam board, a continuous waterproof membrane, a correctly sloped pan and flexible movement joints at every change of plane. Ask how the assembly will be checked before tile conceals it.
We recommend making the concealed work reviewable:
- Review the wet-area scope. It should identify the backing, membrane, pan and movement joints.
- See the membrane before tile. This is the opportunity to review work that the finished surface will hide.
- Photograph every open wall. Preserve the locations of pipes, framing and blocking before closure.
- Coordinate the finish details. Check transitions and choose grout against a wet sample board.
Tiling over existing shower tile buries whatever waterproofing is already there. A new surface does not establish the condition of that hidden assembly. Resolve the waterproofing approach before treating an overlay as a remodeling option.
Ventilation should be sized to the room, ducted outside and controlled by a timer or humidity sensor. In a shared bathroom, back-to-back bathing makes dependable moisture removal especially useful. Fan placement and duct routing belong in the plan before walls close.
What moves the cost, and how should you plan the schedule?
The first budget question is whether fixtures can stay where they are. Moving plumbing is the largest single cost variable, so compare that decision before selecting tile or fittings.
What moves the cost
| Decision or condition | Why it changes the scope | What to resolve first |
|---|---|---|
| Moving plumbing | Changes drain and supply locations | Whether improved circulation or privacy justifies the move |
| Pier-and-beam versus slab | Access differs; slab work requires concrete cutting | Foundation type and proposed fixture locations |
| Post-tension slab | Tensioning cables require care | How proposed work can be carried out safely |
| Borrowing adjacent space | Changes bathroom and bedroom or closet boundaries | Both rooms’ finished layouts |
| More tiled area | Expands surface preparation and tile work | Which surfaces need tile |
| Custom vanity | Fits unusual room widths and assigned storage | Final dimensions and drawer requirements |
| Separate vanity alcoves | Adds cabinetry and plumbing coordination | Whether individual zones improve daily use |
What this means for you: compare options by what each buys in daily function. Keeping fixtures in place may contain the scope; moving them may be worthwhile when it resolves a lasting privacy or circulation problem.
A Jack and Jill bath runs through the same stages as any full bathroom. Design and selections typically take 4–8 weeks. For comparison, on-site construction for a full primary bath typically takes 4–8 weeks; how long a shared bath takes depends on whether the plumbing moves and how much space is borrowed.
Frameless shower glass takes 2–3 weeks after the tile is finished and measured. Highland Park or University Park permit review is added. We set the schedule for your bathroom once the scope is drawn and the selections are made.
University Park households often plan around school calendars. Summer is the obvious window and the busiest; a summer-only project must be genuinely small, with every selection closed before work starts. Decide how the children will bathe during construction before choosing that window.
How Chateau Concepts handles a Jack and Jill bathroom
A Jack and Jill bathroom crosses several disciplines. A cabinet or showroom plan can help organize products, but ask whether it includes the whole room: bedroom entrances, plumbing, waterproofing, lighting and construction coordination. A general contractor manages building work; an interior designer develops the layout, storage, elevations and selections. Confirm who owns each responsibility before hiring.
At Chateau Concepts, Jan draws the plan and elevations, makes selections with the client, then runs the build as general contractor. We schedule trades, pull permits, check work against approved drawings and provide one weekly update. Our bathroom remodeling in Dallas includes primary baths, Jack and Jill baths and powder rooms, from layout through the last fixture.
Jan has practiced interior design in Dallas since 1997 and founded Chateau Concepts, LLC in 2001. She holds a BFA in Interior Design from the University of North Texas. Chateau Concepts, LLC is registered with the City of Dallas as a general contractor and carries general liability insurance; certificates are available on request.
If you already have a builder, we also offer design-only engagements and hourly remodeling consulting for plans and selections. Our guide to who should design your bathroom remodel helps you choose the right arrangement.
