AI for bathroom remodeling companies: in-home sale to final walk-through.

The first clock starts when the homeowner signs. A sale made in the home carries a federal cooling-off period, and in some states a stricter one, so the contract file has to hold the right notice, a deposit inside the limit and a start date that respects the window. The second clock starts at demolition. In a gut remodel, waterproofing has to be finished and accepted before tile goes on, and the shower glass cannot be measured until the tile is done.

The desk work behind both clocks is checking and preparing: a packet compared with the owner's checklist, a start date read off the owner's table, a tear-out photo turned into scope wording, and the next trade's booking drafted after a sign-off is logged. Supervised AI assistants can carry that part. Selling, pricing, reading consumer law, accepting a membrane and deciding who pays for rot are not desk work.

Many bath companies run one of two models, and some run both. The fast-turn model sells a defined product, such as a tub-to-shower conversion with a surround, a shower base and grab bars, at an in-home appointment, often with financing, and installs it in a short window. The gut remodel is designed, selected and contracted over several meetings, then permitted, demolished to the studs and rebuilt trade by trade.

According to its documentation at docs.x.ai, Grok Bot lets a bath company create named Bots, each with one job, that work on a persistent cloud computer and leave drafts and checklists for a person to review. Its documentation describes no telephony, so setting appointments, confirming them by phone and answering a homeowner's questions stay with the setter, the salesperson or the owner. Routines run on schedules at least five minutes apart; nothing here responds the moment a lead arrives.

What the assistants work from is what the business has already captured: the lead form, the salesperson's measure sheet and photos, the signed contract, the financing documents, the installers' notes. Getting at the CRM, the e-signature service or a financing portal means a custom integration for each system, which depends on that vendor's API or terms and has to be tested, or a Bot working the vendor's website in its browser under supervision, again only where the vendor allows it and once tried. Whenever one of those sites asks for a login or a payment step, a person takes control of the Bot's computer and does that step.

Based on the Grok Bot documentation at docs.x.ai as checked on 15 October 2026. Its statements on Bot rules, Bot-to-Bot messaging, routine triggers, connected apps, approval expiry and payments were rechecked against docs.x.ai and Cursor's help pages on 26 October 2026. The trade examples are Aevrion's illustrations, not documented Grok Bot use cases. Aevrion Ops is an independent consultancy. It is not affiliated with, endorsed by or a partner of xAI, SpaceXSI or Cursor. Grok Bot is named here only to describe it.

An in-home sale may be covered by the FTC's Cooling-Off Rule: as checked on 15 October 2026, a buyer who spends twenty-five dollars or more in a sale at home has until midnight of the third business day to back out, and states may add rules of their own; California, for one, caps the down payment and sets its own notice. The paperwork guide in this series sets out both rules and the packet check line by line, and the owner confirms which rules apply in each state the company sells in, with a lawyer.

A packet check is a natural first job for an assistant, because it is the same comparison every time. The Packet Bot compares the notice, the cancellation forms, the deposit, the financing documents and the start date in each signed file with a checklist the owner wrote, and reports what is missing or does not match. The checklist is Aevrion's design rather than something Grok Bot ships with, and the Bot never interprets the law for a customer.

Counting business days is where good intentions fail: the federal rule skips Sundays and federal holidays but counts Saturdays, and a state rule can run longer. So the owner, with legal advice, writes the windows down once per state, together with the company's own policy on ordering and installing while a window is open. The Packet Bot writes the earliest permitted date into the job file and sends any sale the table does not cover to the owner; the Scheduling Bot drafts bookings only from that date, and a person confirms each one with the homeowner. The fast-turn week guide shows the arithmetic across one week's sales.

Damage found when the old tub comes out is a change order: the installer's photos, attached by the owner, become a scope draft, the owner prices it, and in California the CSLB requires the change order to be written and signed by the customer and the contractor before the change, as checked on 15 October 2026. The fast-turn week guide follows one such discovery through a day.

Older houses add a flag. EPA's RRP rule requires anyone paid for work that disturbs painted surfaces in homes built before 1978 to hold the RRP firm credential, with trained workers (as checked on 15 October 2026). A Job Docs Bot can raise the year-built flag on every job file so the owner sees it before demolition. The RRP article in the painting series covers the records in detail.

A gut-remodel bath stacks its trades in a small room. Many bath companies write the order down as a rule: rough-ins inspected, then the waterproofing membrane installed and, where the specification calls for one, flood-tested, then tile, then the glass measure taken from the finished tile, then fixtures and glass. Each step is a sign-off by a person, and the next booking is drafted only after that sign-off is logged. The sequence below is Aevrion's design for that chain.

1. 01

   Rough-in inspection

   Decides

   Has the inspector passed the plumbing and electrical rough-ins?

   Output

   The result, logged by the person who attended; the Bot drafts the waterproofing booking only after it

2. 02

   Waterproofing

   Decides

   Has the person responsible accepted the membrane, with a flood test where specified?

   Output

   A sign-off and photos in the job file; no tile booking before it

3. 03

   Tile

   Decides

   Is tile complete, including the shower walls and curb?

   Output

   Tile completion logged by the lead installer

4. 04

   Glass measure

   Decides

   Can the glazier measure from finished surfaces?

   Output

   A booking draft to the glazier, sent by a person once tile completion is logged

5. 05

   Fixtures and glass

   Decides

   Have the trim, fixtures and glass been installed and checked?

   Output

   A punch list for the final walk-through

Bathroom fitters in England work under a different electrical regime. Part P of the Building Regulations is explained in Approved Document P (2013 edition), and its regulation 12(6A) makes only three kinds of home electrical work notifiable: a new circuit, a replacement consumer unit, and additions or alterations to existing circuits in a special location. In a room with a bath or shower, that special location is the space around the bath tap or shower head: 0.6 meters out from the edge of the tub or tray (or 1.2 meters from the shower head where there is no tub or tray, as in a level-access shower), and up to 2.25 meters from the floor, or higher where the shower head is. Apart from a consumer unit, replacements, repairs and maintenance are not notifiable, anywhere in the house (all as checked on 15 October 2026).

Notifiable work is signed off by one of three routes the document names: self-certification by an electrician registered as a competent person, a registered third-party certifier, or a building control body. For the back office this is one more line in the job file: whether the work is notifiable, which route it takes and whether the certificate has arrived. The owner and the electrician decide; the assistant records it and lists what is outstanding before the final walkthrough.

The documentation recommends the smallest useful roster: one Bot that owns an outcome end to end, with specialists added only for stable, distinct roles. In a bath company the packet check earns the first slot: nothing should be ordered from a file that is not complete. A Scheduling Bot and a Job Docs Bot follow once the packet check is reliable.

Two account-level facts shape the setup. All of the account's Bots share a single cloud computer, including its files and saved browser logins, and the Grok Bot documentation warns against treating separate Bots as a security boundary; a financing portal or e-signature account left signed in there is reachable by the Packet Bot and the Scheduling Bot alike, and real separation means a second user account. An approval that an evening routine raises with nobody watching lapses after roughly ten minutes (Cursor's help pages say thirty) unrun, so the evening packet check ends as a list on the owner's screen, never as an order or a booking.

Each of these has a named person in the job file, and the Bots stop at every one.

• PRICE AND FINANCING

  The price, any financing offer and every term discussed at the table belong to the salesperson and the owner.

• CANCELLATIONS AND REFUNDS

  A cancellation received is handled by the owner; the assistant flags it and stops all drafts for that job.

• WHAT THE LAW REQUIRES

  Which rules apply and how a window is counted are settled in the owner's table with legal advice, never by an assistant.

• ROT AND STRUCTURE

  Whether a floor needs repair, and what it costs, is the installer's and the owner's call.

• WATERPROOFING ACCEPTANCE

  Only the person responsible accepts the membrane or the flood test.

• ACCESSIBILITY ADVICE

  Grab-bar positions or a curbless entry are recommendations a qualified person makes from the homeowner's stated needs.

• ELECTRICAL WORK

  Whether the work is notifiable, and which route it takes, is decided by the owner and the electrician.

The useful first step is a look backwards: take the last ten in-home sales and check each against the federal rule, the owner's state rules and the start dates actually booked. That shows whether the gap is the packet, the start-date arithmetic or the hand-offs between trades, and it produces the checklist the first Bot will use.

Aevrion Ops can then turn the audit's checklist and start-date table into a working packet check, size the roster around it, and connect the CRM, e-signature and job-management tools the company already pays for, wherever a vendor's API or terms permit and only after a trial run. The workflow automation readiness assessment is the place to begin.

1. A bath company runs two clocks: the cancellation window that starts at signing, and the trade stack that starts at demolition.
2. Under the FTC's Cooling-Off Rule a buyer at home who spends twenty-five dollars or more can back out up to midnight of the third business day; states may add more.
3. A Packet Bot checks each in-home sale file against the owner's checklist and never interprets the law for a customer.
4. The earliest start date comes from a table the owner writes with legal advice; the assistant applies it and stops on anything the table does not cover.
5. In England, Approved Document P (2013) makes only a new circuit, a replacement consumer unit and additions or alterations in a special location, such as the space around a bath or shower, notifiable; other repairs and replacements are not.
6. In a gut remodel the next trade is drafted only when the previous sign-off is logged: waterproofing, then tile, then the glass measure.
