Не надо ничего удалять и создавать заново. Надо просто расположить окна одно над другим и показывать нужное в нужный момент:

import tkinter as tk


class WizardLikeApp(tk.Tk):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        container.grid_columnconfigure(0, weight=1)

        self.frames = {}

        for F in (StartPage, PageOne, PageTwo):
            frame = F(container, self)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky='nsew')

        self.show_frame(StartPage)

        frame.tkraise()

                           command=lambda: controller.show_frame(PageOne))
